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.
