Bitcoin mining really no longer profitable, even with multiple GPUs ?

[Patikno]

As I recall, when I first learned about Bitcoin, I could still see a GTX 1080 GPU as being profitable (though not very much). However, it seems like it is no longer profitable. Maybe, because ASICS miners are involved in the mining process forward.

Based on whattomine, it seems like the latest GPU series are mostly used for mining shitcoins nowadays.

So, I have a question: is Bitcoin mining really no longer profitable even with multiple GPUs ? or, is it better to use many small bitcoin solo miners ? ( which we know as lottery mining )

Yes, bitcoin mining is no longer profitable with GPU. I have been seeing posts that bitcoin mining is no longer profitable after bitcoin halving in 2020. Miners have all moved to ASIC which has generate higher hashrates.

or, is it better to use many small bitcoin solo miners ? ( which we know as lottery mining )

Can you explain this better. You mean using many GPUs? No, get many ASICs instead.

Please ref https://bitcointalk.org/index.php?topic=2415854.msg24714338#msg24714338 mainly point-3.
Since 2013 when ASIC-based miners came out all cpu, gpu, and even FPGA miners became hopelessly out classed. Even today's fastest and most powerful GPU's from Nvidia et al are still thousands of times slower than the first ASIC-based miners from back then.

I don't know why you came up with mining BTC with GPU even a decade ago. GPUs were only considered good for altcoin mining but never for Bitcoin.

You might be thinking, "NiceHash" mining with GPU rewarded you in Bitcoin, but the fact is you are mining an altcoin they only pay you in Bitcoin. Before it is profitable around 2017, I build my gear at that time to mine ETH or mine in Nicehash. It was profitable until the price of coins dropped and mining with GPU was no longer profitable due to high electricity rates.

1080ti: This is a power-hungry GPU. I sold my rig with that GPU, including the script to improve the hash rate a bit for this GPU. It is not worth having this GPU that eats too much power.
You better rent them out instead because they pay well based on what I heard in "Vast.AI" but I won't guarantee it could be profitable because I never tested them after I sold most of my GPU and built a few of them to PC to sell.

Your memory is wrong or you were misled by someone else. According to Wikipedia, that GPU released in May 27, 2016. By that time, every miner only use ASIC.

Yeah. Other popular coin have moved from PoW (for example ETH moved to PoS), while Monero switched to RandomX which makes it's profitable only with CPU.

It's also worth to mention NiceHash have become worse platform since few years ago. I recall it's because some inactive/withdraw fee and identity verification even if you only mine and withdraw BTC.

Well, that's the worst thing they did. Now asking for KYC seems risky since they have past issue about the breach before around 2017. I remember that day that is why I switched mining altcoins directly from the top pool listed on miningpoolstats and a few of them on viabtc because they  have option to auto convert my coins into BTC.

If they are legal businesses that follow regulation, they should also be aware that we have different legal jurisdictions.

Unlike known mining pools like F2Pool and ViaBTC, KYC is not mandatory, and other pools must do the same since Nicehash doesn't act as financial intermediaries but it supposed to act like other pools since all coins are newly mined and they aren't mining them from users.

I don't know much about regulations, but how does where users live matters for them? Wouldn't they follow the regulations where they run/register their business? For example, many overseas exchanges don't follow my country laws related to KYC. I guess things will differs if they opened a branch here, but that seems unlikely.

On their KYC page, they claims their KYC is only for Easy and Team mining rewards[1]. It's basically the service where users buy hashrate from others (unlikely from GPU power for Bitcoin though, CMIIW). Do they also apply this if you're mining on your own?

It is still possible to use GPU if that's all you have, whattomine is simply telling you one thing only, that you can mine those shitcoins and convert them back to Bitcoin, or use nice hash mining OS to mine shitcoins using your GPU and then get paid in Bitcoin, it's not directly mining Bitcoin but it's a workaround that I have done for two years straight in the past, don't let your inability to get Asic miner gets in the way, you already have some GPU? Good, this is a workaround that's not bad, unless your electricity bill sucks.

I currently can't access that page directly. But based on archived page few months ago, their wording is confusing.

KYC is mandatory for all users on NiceHash. All users must complete KYC to claim the block reward from Easy and Team mining services.

I would assume the first sentence is more accurate wording, since it match what some NiceHash user claim.

don't let your inability to get Asic miner gets in the way, you already have some GPU? Good, this is a workaround that's not bad, unless your electricity bill sucks.

Besides electricity, people need to check whether their GPU is new or efficient enough for such task and consider risk of the altcoin price volatility.

Forget about mining with old graphics cards unless your electricity costs are close to zero.
You could use software to mine shitcoins that offer the highest potential returns, while receiving your rewards in Bitcoin or other coins; however, you would only earn about $12 a month per 1080 graphics card. That is a very poor result.
