Bitcoin Gold a Shitcoin Vulnerable to Attack Despite $200 Million Market Cap

Bitcoin Gold a Shitcoin Vulnerable to Attack Despite $200 Million Market Cap

https://cryptoiq.co/bitcoin-gold-a-shitcoin-vulnerable-to-attack-despite-200-million-market-cap/
The War On Shitcoins Episode 1: Bitcoin Gold (BTG). The war on shitcoins is a Crypto.IQ series that targets and shoots down cryptocurrencies that are not worth investing in either due to their being scams, having serious design flaws, being centralized, or in general just being worthless copies of other cryptocurrencies. There are thousands of shitcoins that are ruining the markets, and Crypto.IQ intends to expose all of them. The crypto space needs an exorcism, and we are happy to provide it.
There are more than 2,000 cryptocurrencies listed on CoinMarketCap, and Bitcoin Gold (BTG) is near the top at number 25 with a market cap of $207 million. This would seem to indicate that Bitcoin Gold is a major cryptocurrency, but it is simply a copycat of Bitcoin with one key and debilitating difference that makes it worse than Bitcoin. Bitcoin Gold is designed to block ASIC miners, leaving only GPU miners.
The idea was that GPU miners would rally around Bitcoin Gold since GPU Bitcoin miners were disenfranchised by ASIC miners years ago. Ultimately, this decision to only allow GPUs resulted in such a low mining hash rate that Bitcoin Gold is vulnerable to 51 percent attacks, and a serious 51 percent attack has already happened once. Further, Bitcoin Gold has had centralization problems from the very beginning.
When Bitcoin Gold launched in November 2017 the developers did a massive premine of 8,000 blocks, which yielded them about 100,000 BTG. At today’s price $12 this is $1.2 million, and when BTG’s price peaked near $500, this was $50 million. This premine is unfair to other BTG miners, traders, and investors. Supposedly, the premined BTG were placed in an “endowment,” which means the developers will receive all of that money eventually, just not all at once. There is no way to verify if this is even true, however, and the excessive 97 percent BTG price crash since January 2018 might be partially due to developers dumping their coins.
A far more serious issue than the premine is BTG’s lack of network security. BTG made mining ASIC resistant by using the Equishash Proof of Work (PoW) algorithm. However, ASICs were eventually developed for Equihash since ASICs can be developed for any PoW algorithm. In May 2018 a 51 percent double spend attack occurred on the Bitcoin Gold network, and a hacker stole $18.6 million from cryptocurrency exchanges that listed BTG. This caused the developers to hard fork in order to implement a newer version of Equihash that is supposedly more ASIC resistant. Clearly, the developers did not learn their lesson that there is no ASIC-resistant PoW algorithm. If Bitcoin Gold became valuable enough, someone would produce an ASIC for it.
It is unclear if Equihash ASICs were the reason for the 51 percent attack, since an attacker could literally just rent some hash rate on a cloud mining site and successfully 51 percent attack Bitcoin Gold. Currently it only takes 1.6 MH/s of rented mining power to successfully perform a double spend attack on the Bitcoin Gold network, and this costs about $1,000 per hour if the hash rate is rented from NiceHash.
Effectively, Bitcoin Gold is not cryptographically secure. The original purpose of banning ASIC miners so that GPU miners could thrive ended up being a fatal flaw for Bitcoin Gold. It is ridiculous that major exchanges like Binance and Bitfinex still offer BTG trading. This is a true disservice to the users of these exchanges and is a risk for the exchanges themselves.
Crypto users need to educate themselves thoroughly before buying any cryptocurrency, or they could end up buying a shitcoin like Bitcoin Gold just because it has a high ranking on CoinMarketCap. BTG has already lost 97 percent of its value since January 2018, and there is strong potential for it to become completely worthless once someone decides to rent some hash power and perform a vicious 51 percent attack.

bitcoin-digi.com - Bitcoin News - Need Help With Site Direction For Bitcoin

Hey guys,
I am making a new website called bitcoin-digi.com were we can all discuss about bitcoin,bitcoin price,bitcoin news,bitcoin value and a converter to for bitcoin to usd.
I was thinking about having live bitcoin price updates which I have already posted. Along with allot of great information about the antminer s9 and any other s9 bitcoin miners.
I think if we call can input real bitcoin news we can come to a bitcoin value reality with discussion.
I also want to create a discussion board about any new ASIC bitcoin miners or GPU bitcoin miners coming to market and talk about bitcoin mining.
I also have youtube videos for antminer s9 setups and will incorporate videos about the a3 antminer setup for antminer a3 whatever we want to call it =)
I really appreciate and good advice on what else to add to the site to help others.
The site is: http://bitcoin-digi.com/
Any input is greatly appreciated guys.

Why Litecoin is Set to Skyrocket

*TL;DR Miner migration to litecoin, litecoin's similarity to proven bitcoin, relatively low market cap, Mt. Gox's API's will soon support litecoin, and litecoin's utility as a very liquid form of money is set to cause litecoin's price to skyrocket. *
Read more at http://zamicol.blogspot.com/2013/04/why-i-think-litecoin-is-set-to.html
Excerpts:
Market Cap
With 333201 blocks mined, and 50 litecoins per block, there is currently 16,660,050 litecoins in circulation. The current market price of $2 USD gives Litecoin a market cap of over $33 million.
This may sound like a lot, but considering that after the “crash” of the past couple of days, Bitcoin’s market cap about $1,157 million USD with the current market price of $98 USD. If litecoin had the market cap of bitcoin, each litecoin would be worth over $69.
Granted, this may not be a fair comparison, since in litecoin’s youth it has not experienced the same proportion of inflation as it’s older brother. While bitcoin is already over its halfway mark to generating its limit of 21 million bitcoins, litecoin is much younger and has not reached the halfway point to its limit of 84 million litcoin. If we factor in that there will be four times as many litecoins as bitcoins, each one of the 84 million litecoins would still be worth over $13 if litecoin had the bitcoin’s market cap.
Litecoin Mining Difficulty
A while back, my ears perked up at the prospects of litecoin because of a new technology is set to give the market a good shaking.
As anticipated, the increase of difficulty of Bitcoin is causing traditional miners to look for more profitable outlets for their existing infrastructure. Hundreds of ASIC miners are now active, which has forced up the difficulty dramatically to an all time high of 7,673,000 with the next difficulty estimated to be near 9,000,000. News of the impending deployment of thousands more is forcing miners to rethink their allocation of existing infrastructure.
Faced with bitcoin’s increasing mining difficulty, GPU Bitcoin miners have three options:
Keep mining bitcoin at a potential loss as electricity costs become much greater than the return on mining. Turn off their miners and sell or retire their hardware. Look for more profitable applications for their existing infrastructure, such as litecoin.
This is where the power of litecoin is very apparent. Due to it’s use of the memory intense scrypt algorithm, dedicated litecoin hardware like ASIC miners are not anticipated in the near future, giving GPU miners a window of opportunity for profit. Switching their GPU hardware from bitcoin to litecoin is only a matter of installing a new mining application and can be done with little configuration. The logical choice for most bitcoin miners will be to move their power to the litecoin network.
In the short time I have been litecoin mining, I have seen the difficulty rise over 600%, meaning that there is six times more computing power dedicated to litecoin in only the past few months. This indicates that many miners have already made the realization that bitcoin offers them a bleak future and made the switch to litecoin. As these miners transition their hardware, litecoin’s mind share will increase, and it shouldn’t be a quickly passing event. Miners can take confidence in litecoin knowing that their infrastructure will be valuable for the foreseeable future, and this confidence is bound to poor over into the market price of litecoin.
As an early bitcoin miner, I remember the supply of ATI 5870’s graphic cards quickly becoming unavailable as individuals bought up supply for use in bitcoin mining. This infrastructure still exists and it will not go to waste.

3 Types of Bitcoin Mining Hardware

There are two options for mining Bitcoin: cloud mining and hardware mining. While cloud mining has to do with mining remotely without physical mining equipment, hardware mining comes with the full package. Most people prefer to set up a Bitcoin miner as it is more profitable than cloud mining in some cases. If you want to set up your Bitcoin miner, you need to know that it is expensive and upgraded versions are made now and then.
Types of Bitcoin Mining Hardware
  1. CPU/GPU Bitcoin Miners
Although this was the first type of Bitcoin mining hardware accepted into the mainstream, it is now considered the least powerful. You’d be using the CPU of your computer to mine Bitcoins. By adding GPU hardware to your computer, you will be able to enhance the hash rate. However, the Bitcoin mining difficulty has increased so much that people can hardly make any profit for CPU/GPU mining.
  1. FPGA Bitcoin Miners
FPGA stands for Field Programmable Gate Array. It is a circuit designed for configuration after building. This allows hardware manufacturer to buy chips in volumes and customize the chips for Bitcoin miningbefore installing them into their equipment. The performance of this hardware is far better than that of CPUs and GPUs.
  1. ASIC Bitcoin Miners
Of the three types of Bitcoin miners, ASIC is the best. ASIC stands for Application Specific Integrated Circuits. They are designed specifically for the sole purpose of mining Bitcoins. They are extremely fast and consume relatively low power compared to the others. Although they are expensive, the miming speed of these miners is mind-blowing

A reminder why RandomX and commodity hardware mining is so important

Authorities in Venezuela will "supervise both the creation and importation of mining equipment" and force miners to use only national mining pool, source. Governments can control ASIC mining, but they can't control CPU or GPU mining to the same extent.

Should a Student get into BTC Mining?

Hey Bitcoin Miners, I'm thinking about starting mining bitcoin since my electricity is included in my Student Apartment Rent and I cant find anything on my contract any minimum for electricity usage. I am already paying an overpriced rent so I dont feel bad for profiting off it. I'll be staying here for about 3-4 years so I want my Mining Rig to be paid off in less than a year if possible. Do you think I should get into BTC Mining? I could invest a little over 1000$ for the rig, any recommendations?

Newbie Question: How do I get started with mining?

I know I should probably wait for a referral link, but I've already read a lot about mining and I have a few questions. I would like to know some more about the bitcoin mining process, mainly about the profitability of it. What are the best settings for a CPU, GPU, and ASIC? Are there ways to get some mining bitcoins without paying for mining hardware? I know there are "miners" like cgminer, but what's an alternative? Thanks!

Why Ethereum Mining?

1. High market capitalization, second to bitcoin only
Ethereum is the most dynamic blockchain platform in the world, and Ether is the second largest cryptocurrency in the world by market capitalization. There are around 1,200,000 transactions processed per day on this platform. Numbers explain everything.
https://preview.redd.it/w57fpy6njvp51.png?width=398&format=png&auto=webp&s=dbac1c20eaa78a503b71c8f667b12293f9079208
2. Dapps on Ethereum outnumbers any other blockchain platform
Not only just a digital currency or commodity, ethereum also keeps its original motivation to be a global computing platform that allows users to deploy smart contract on it. As a kind of smart contract programmed for a specific use, there are about 2 ,000 decentralized applications, or dapps, deployed on ethereum by this June, which is more than the total numbers of dapps deployed on any other general purpose blockchain platform in the world combined.
https://preview.redd.it/vau9ezssjvp51.png?width=461&format=png&auto=webp&s=02f121dce31a405802721a878a74a7b3e16cde14
3. Considerable payback
ETH mining profit basically consists of two parts: the value of the coins and the transaction commission. Once you mined a block, you will not only get the coins, but also the commission to prove the transactions that will be processed in the network. Because of the network congestion brought up by DeFi application ‘s popularity, transaction commission contributes much to the mining profit recently.
(Averages on 17th September,2020:
Ether Price: $389.49
Gas Price: 538 Gwei
Gas Limit:12,472,107
*Commission=538*12472107=6,709,993,566Gwei≈6.71ETH)
https://preview.redd.it/exsbhw4ujvp51.png?width=399&format=png&auto=webp&s=b781f5ab2bac90304fd3be021def54501ba7252b

Below is a profitability ranking of ASIC miners for some mainstream crypto coins when Gas price is around 60~70Gwei and coin price is about $360. I couldn’t find a ranking that could include all AISIC miners and GPU miners, but it’s enough to show that ETH mining is much more profitable than others. Even though when Gas price and coin price is not very high, the revenue of ETH mining still beats other mainstream cryptocurrencies.

4. Lower Network Difficulty
Compare to bitcoin network hash rate, Ethereum network hash rate is only 244.14TH/s; Less network hash rate means less difficulty, furtherly means that there will be more chance to mine a block and get coins. Nowadays, for bitcoin mining, the possibility to mine a block solo is almost zero, but for ETH mining it is still possible. In my opinion it is the golden time for ETH mining.

Whether you are a new bird or an experienced senior in this field, ETH mining is the best choice in 2020.

Trying to decide weather or not to get a Z11, S19 or S9. Opinions wanted.

Edit I ment type Z11 S17 or A9 (freaking autocorrect)
I'm looking to buy a profitable ASIC with a $2000 budget. And I'm looking for you reddits knowledge and experience to make sure I'm going down the right path.
So far I'm leaning on purchasing a Antminer Z11. The price is reasonable and the profitability looks good.
Another choice is the infosillicon A9. They are probably the cheapest miner that turns a profit, and the low wattage consumption is attractive so I don't have to upscale my electrical right away. If I chose the A9 I would buy 2 or more.
Third choice is the s17. It's more expensive and less profitable but it mines bitcoin. And I wonder if there's any unforeseen advantage of mining bitcoin should it moon shot.
GPU's I have a GPU rig running right now, and I plan on adding to it, but really want to dive deeper into ASIC mining right now.
Thoughts?

Where can I get help for 3080?

My 3080 was running fine and randomly mid game I lost half my frames and gpu was hot. Basically I found out it runs at full frequency doing nothing. just on desktop basically now it is stuck at full power but nothing is using it. I don't wanna rma because I asked and they said turnaround time is around 1-2 months, and no thanks. it is stuck at 9501 on memory and 1740 for core. I have a msi 3x oc 3080 ventus. pictures. I really need some help. I have been trying to solve this problem for 4 days ongoing. I reset windows 4 times, thought it was a bitcoin miner virus. I couldn't find anything with any virus or rootscanners and I doubt its a virus since resetting my windows 4 times and clearing my ssds wouldnt let it survive. Also it goes back to normal frequency when resetting windows but comes back after like 5 minutes. during those 5 minutes the frequency memory and volts are normal but whenever I open any 3d application, chrome, any program. it shoots up to max load for one second and then goes back to normal. then later it just stays at full load infinitly. please someone help. The only thing in task manager that uses .5 usage of gpu is desktop windows manager, system, and client server runtime process

Why the 3070, 3080, and 3090 are going to spike in price.

Why the 3070, 3080, and 3090 are going to spike in price.
I was one of the lucky few to get a 3080 on release and I have stressed tested everything I can think of out of this card. It is absolutely a monstrosity. I happened upon an article saying the 3080 and 3090 have terrible MH/s(hashrate/mining rate for mining bitcoin). I decided to see what this card can do and happened upon some interesting data. So I decided to use Nicehash to test the GPU mining profitability(I'm sure its off by some margin but its a good start.) After running for a day and with the correct downclock I can keep my temperature stable. Increasing the power limit past 70 yield marginal hashrate at the expense of a significant amount of power(it becomes less profitable). With my current electric bill(around 11 cents per mwh) I make 2.20$-2.40$ a day after electric expense. A more sophisticated miner could make more with the right software(linux) and lower electric rate. Just wanted to share my opinion I could be wrong, let me know what you guys think.

Building an ASIC miner with FPGA chips or manufactured IC's available on the market

Hi again. I recently made a post on using Arduino to replace bitcoin miners and i realized how crazily stupid that decision would be seeming as a typical Arduino has a hash rate of around 50
Now I needed a new way to build an ASIC miner seeing as Arduinos are out of the question. The two possible methods I came up with/discovered was by using multiple FPGA chips to do the exact calculations needed.
The other is by using pre-manufactured IC's from older GPU's, buying them in bulk and building many GPU's that are built around those IC's
I have three questions:

About Bitcoin mining in Egypt and GPUs

Hello,
Just wanted to make a post discussing this matter in Egypt. I hope someone from government also reads reddit.
I can understand logical reasons why Egypt would want to prohibit Bitcoin mining:
  1. Paying electricity at subsidized price and then selling Bitcoins for money means you're stealing the subsidy.
  2. Untraceable Bitcoin can be used for criminal activities or terrorist finance.
  3. Income from Bitcoin mining is not official and counts as income, so taxes are not being paid on it.
Since they suspect people who buy GPUs of doing this, I propose the following:
  1. Let people declare that they are mining Bitcoin and remove electrical subsidy from them (let them pay the highest electricity tier price). Let them also count the electricity as expenses to avoid double-taxing.
  2. Require that the wallets that receive the mining proceeds be made known to the government.
  3. Open a local Egyptian Bitcoin exchange and when mining bitcoins are sold for EGP, count the EGP as capital gains or income and make people pay taxes on them as such.
  4. Prohibit any transfer of those bitcoin between individuals and allow the only action to be done on them is keep them or sell them on a legitimate exchange which requires KYC/AML.
Instead of causing unnecessary headache for people who want to simply buy a GPU to play games by stopping or delaying all GPUs being imported, simply require that the imported GPUs be registered to the individual name (file automatically opened by customs without need of input from the importer), and set a limit for the number of graphics cards imported annually for individual use.
In addition, for people who are not registered as bitcoin miners (or doing high electricity load work), if there's an unnatural large increase in the electricity consumption suddenly that doesn't coincide with a legitimate reason (eg: summer time and start of use of Air Conditioners) and the increase goes beyond the level historically consumed by the residence, then you can suspect that they are mining bitcoin, and then you can then investigate them.
This way, both the government requirements can be satisfied and at the same time, people who just want to play games or do 3D work do not need to be unnecessarily harmed or impeded by regulations.
This post can be considered as an open letter to anyone from authorities.

Will there be any perfect timing?

I wanna build a new pc for myself, I don't play a lotta AAA titles but I only love racing games and a little RPG adventure type games and world. I liked NFS heat and forza and I wanna play them on a fairly lag free setting. Upon my research I thought Ryzen 2600 is the cpu for me but seeing the current situation everything is so much pricey I saw YT videos of 2600 for around 8k or less, but now it's over 12k and don't get started on GPU with the 1660 super costing 22k. I remember I wanted to build previous year or something but prices went up because of bitcoin miner buying GPU in bulk. I don't know I feel like prices can never be on a sweet spot. I think I would wait till the black Friday sales or something but will it make any difference here in India ?

Some sites to make extra money

Hello Fellow Redditors,
I am going to list some of my income sources. I will try to give as much information as I can.
Some details about me:I am u/abhiearns, I am currently studying. I want to create some sort of extra income sources. I have been trying to use beermoney as well as other passive income communities like passive_income, passiveincome to find some sites and sources that can work for me.
Enough with the details, Let start by listing some of my extra income sources.
Active Earning: So, I will start with sites on which you have to work actively and devote some serious hours to earn some extra income. These are some beermoney sites (include survey sites, and other such sites):


Passive Earning (No Initial Investments): These will list some of my passive earning sources, I am not listing my investments here because I think they deserve a separate section.Disclaimer: I have 2 laptops and an extra phone so I use all of them for earning, the payments may vary depending on the number and power of various computers.




Passive Earning (Investments Required): These are the sources which require some sort of initial investment. These sources can be risky and there are chances to lose money.



\** I am still trying other sites and apps. I will keep updating this post.*
These are some of the sources I use to earn, I highly recommend these. I won't say you will become a millionaire using these but still its little more than you had yesterday.

What do you guys think about the possibility of using lots of Arduinos to possibly replace expensive GPU's in bitcoin mining

I'm not sure what I'm talking about here too much but I'm pained to see expensive GPU's that the ultra-rich buy in the thousands and mine so much bitcoin.
My attempts of bitcoin mining with my PC were a failure because my 4GB GPU is not strong enough at all
Renting ASIC miners are mostly scams and I will not get much return
The one thing I'm forced to go to is to make my own GPU by my self and see if there is a possibility of working a with a general PC
As far as I'm aware this has never been done before and by no means do I expect an Arduino graphics card to be as strong as an early 2000's GPU but my thinking is: If I can buy the components for a cheap price then I can assemble an array of weak GPU's to become a far stronger one

If this whole idea is a flop and there is no real way to make money, I want to use this as a learning experience
So the first thing I want is a discussion on whether or not this could even achieve and become compatible with a PC. Whether it be a gaming PC or a raspberry Pi
The next is some sources on how GPU's work and their pinout and whatnot
I really don't expect any positive comments in this comment section since what I'm thinking of doing is near enough outrageous Xd

Effects of ETC moving to SHA3

0xBitcoin might experience some benefits from ETC's recent decision to go to SHA3.
For one thing, if ETC developers turn their minds toward SHA3 GPU mining, it seems likely that they'll be very interested in the optimization work already done by Lt. Tofu and Azlehria on Cosmic and Nabiki. But they may also spot additional optimizations, which could most likely be ported back into our miners!
For another thing, since ETC has a larger community than 0xBitcoin's, it's likely that they have people with very diverse skills. As they turn their minds toward SHA3 on FPGAs, I anticipate they will be choosing FPGA boards and writing software for them that probably will not be very difficult to alter to mine 0xBitcoin! Practically speaking, this may result in a new era of mining where a respectable hash rate can be achieved with much less electricity expense.
Basically, if people with EE or hardware development backgrounds in the ETC community pin down some of the variables involved, like development board, it seems very likely that we will be able to get FPGAs mining 0xBitcoin quickly.
We recently exchanged some nice words with Alex Tsankov. He revealed he is doing work that may allow merge mining ETC and other projects like 0xBitcoin. I don't know how good this will be, but it's hard for me to see how this could be a bad thing. It's really great to have nice words from Alex, because he seems like a very smart dude who is very open to collaboration.
I have joined the ETC Discord (edit: link removed for just-Reddit-things reasons, you'll have no trouble finding it) and will be watching for opportunities to tell people there about our miners if they don't know, and watching for info about their developments on SHA3 miners.

I'm having trouble with "crashing"

I don't even know where to begin googling, so I'm posting here in case someone already has an answer while I google ten million iterations of a question.
I built my PC about two years ago. It ran (runs!) great. Then about six months ago it started "crashing." I put that in quotes because I don't know if its the right term, its not like any crash I've been used to. The monitors cut out, the speakers cut out, but the fans and internal lights stay on. The fans even seem to get faster but that could just be because I'm paying more attention to them. Holding the power button does nothing, I have to reach back and cycle the switch on the power supply.
My brother thought it was possibly too small a power supply, but I have a 750, and he immediately nixed that idea. Our next idea was GPU, since I bought a used 1080-Ti. However, I don't have any of the classic signs of GPU failure, no stuttering, no ghosting, no artifacts, no distortion. I should mention that I bought it from a bitcoin miner after the crash, but based on the parameters the seller gave and what I researched, it shouldn't have been taxed too heavily.
I've kind of let it go because it doesn't happen very often, but then last night it crashed four times in an hour.
All I had open was Discord, Steam, and Among Us, so I know its not RAM, I've had waaaay more open with no issue. During the second reboot, I went into the BIOS and all my temperatures were well within the normal range. After the last reboot, I had some stutter on my main monitor, but none on my second, so i unplugged and replugged it and that fixed it. I figure I bumped the cord when reaching down for the power supply switch.

GPU or Asic mining

Ok, A little backround. I know hardware and networking. I can build just about any config of a computer. I understand overclocking and undervolting. I can invest around 2,700 for initial investment.
So do I buy hardware to build a GPU miner with at least 6 cards or more? Probably RX580 as they are cheap and I have one in my rig. More on that later.
Or do I a Asic miner like this I understand a GPU miner is multiple coins and not Bitcoin, and Asic is nothing but Bitcoin.
I've done the math on the Asic miner and the ROI in about 3 months with a net gain of about ~10,000 USD a year @ .13 cents per Watt.
I've had a hard time finding a solid or semi way of calculating the earnings for a GPU miner. Not only because it is many coins or dedicated to one coin, but there our other variables involved. However I have more control of the hardware if it fails.
I dipped my toe into mining with my own rig that has a RX580 fatboy and a AMD Phenom ii x4 955 black edition. I overclocked the GPU and undervolted the CPU to reduce heat since it was hitting 62 cel.
The GPU gets 12.5 sol/s and the CPU was getting ~322 h/s. All this added up to ~170 watts and a net of .00218322 BTC/Month. This was all done using Cudo as it was easy to find and setup just to test. This was just a test to see how it would work. I wouldn't use Cudo to full scale as it is a pool and the transfer to a Wallet is pretty steep in relationship to earns. I understand that in a pool you get your share based upon how much of the "work" you did to get find block.
So do I build or buy? With that much computation power do I need to join a pool? What software is best for pool or alone? I am comfortable with CLI as long as it's well documented, but would like a remote GUI.
Also what is the best wallet with the best fees for transactions. Currently using uphold since I use Brave.
I think I covered as much as I could, if you have any questions let me know. Any advice would be great. If I should post this else where let me know please or I could just cross post it.
TIA. Be safe, stay safe!
Edit: Words and BTC earning was WAY off then I first typed this.

My GPU runs hotter when Idle. The moment I move the mouse it starts cooling down. (Win10 v1903 Build 18362)

Ok so I'm using EVGA Precision X1 to monitor temps and to set my fan curve, works fine. But I noticed that when I go away for a bit and come back my gpu temp will be sitting around 55 degrees with the fan going at ~65%. The SECOND I move my mouse, it quickly starts dropping temp till it sits at 20-25 degrees.
The first thing I can think of is that I have something trying to sneakily bitcoin mine in the background but scans have come up clean. What can I do to see what is responsible for this?
Cheers.
Edit: Solved: Malware bitcoin miner had taken over the file. Quarantined it and the issue disappeared.

LAPTOP PERFORMANCE IS TERRIBLE CONSIDERING ITS SPECS

So when i bought the Laptop everything was fine but now im getting like 40 fps in games and graphics is set lower. Before it was 60fps but on much higher graphics. MY SPECS : Asus TUF gaming FX504 GTX 1050 4GB , Intel I7 8750H , 8gb ram and 1TB HDD. Im thinking it could be due to a) I installed malware by mistake. I downloaded like 5 AV and somehow "removed it" Malwarebytes told me that it was bitcoin miner which affect performance so I tought that was it and I did factory reset but that made it just worse now i cant open NVIDIA control panel and update my graphics driver trough Geforce experience and overall performance is same if not worse . Or b) Some time ago I tried overclocking trough MSI afterburner and EVGA precision and almost killed my gpu but I didnt noticed much diference in terms of fps afterwards . I think its due to overclocking but im not sure. pls help thx

Super bad framerates with a 100% GPU use spike. Can't figure out what's wrong, as temperatures are pretty low.

Super bad framerates with a 100% GPU use spike. Can't figure out what's wrong, as temperatures are pretty low.
Okay, so I've been trying to find out why this is happening for about a week, my machine is a Thinkpad P53 workstation, with a 6-core 12-thread i7-9850H and a Quadro RTX3000 GPU. I know this sub is mainly geared toward desktops, but I didn't know where else to ask, as I believe if anyone would have great troubleshooting skills in this topic, it will be you guys.

So, I've had this machine for almost a year now, no issues until about a week ago. I have 64GB of RAM and 2TB of nvme SSD storage as well, so I doubt there's an issue there. I started playing a pretty non demanding game, Monster Hunter World, and purposefully set it to 1080p and medium settings, whereas I can run it at 4k 60fps no problem with high settings.

The issue happens sometimes after 5 minutes of playing, and sometimes after 30 minutes of playing, it's pretty random, but what will happen is that fps will drop from a solid 60fps to a stuttery 15-20 fps, the important aspect of this is that the exact moment it happens, the GPU usage jumps from around 50% to a full 100% and stays there, not sure what's happening. I know that "100% GPU usage is good" but this case is different. The machine is powerful enough, as I'm pulling 60fps with the highest settings with 50-60% usage, but it only jumps to 100 the exact moment the performance drop occurs.

I downloaded MSI Afterburner and RivaTuner to see it in action and got this screenshot:

Temps are fine, they rarely go above 80-85C ever, as I've repasted the machine.

I took this a few secs after the performance drop, I notice that there's a temp and power throttle, the power throttle is usually there most of the time, and doesn't exactly affect performance, however the temperature throttling is what I find puzzling, as you can see the temps are fine, and stay there pretty much with every game, since it started happening about a week back, I decided to repaste the machine, and even though it helped keep temps much lower than before, it still didn't solve the issue.

After reading several threads here, I couldn't find any which were analogous to "High GPU usage, FPS bad", but I did read about several people that found out they had a bitcoin miner malware in their machine which spiked GPU usage. I decided to completely reinstall Windows in order to get rid of that probability, I made a bootable usb drive with the Windows Install tool and completely wiped all of the partitions before reinstall. The issue remained, so I could count out bitcoin malware, or Lenovo drivers, since the clean install came without any Lenovo bloatware, and also driver issues, so I just upgraded all my drivers back to the newest ones, now here I am, desperate to find out why this is happening, begging for help in pcmasterrace.

Is there any other benchmarks/tests I can run to diagnose the issue? I bought 3dMark, PCMark, and VRMark to benchmark my machine, and ran the time spy benchmark without issues, but only a couple of times, maybe not enough to have it show up.

Lastly, I have the machine plugged in, and on 'Best Performance' mode, which according to the machine, should provide the best cooling instead of caring about being quiet.

EDIT:
I'll also add, that the issues go away after a machine reboot, and sometimes when changing the performance slider from 'Best Performance' to something else and then back. At this point I think it might be driver or BIOS version related, so perhaps waiting might be the key.
