You seem to keep ignoring the fact that you keep calling people liars and when they show that you’re wrong you change the subject back to something to argue about again.
You’re either trolling or just want to argue because you can’t help yourself.
Obviously hardware designed specifically for a task (ASIC/FPGA) will do more than a general purposed device designed for graphics - I doubt anyone is arguing about that.
GPU mining is still profitable so that’s one reason people like it. GPU mining is flexible and let’s you support various coins/tokens for projects that you like and it also means that you get new crypto every day no matter what’s going on with the prices.
I’ve used ASICs but I don’t like them because they’re not flexible and they’re always being redesigned and newer ones come out sometimes faster than you can make your money back. Once new ASICs overtake your current one it’s just a paper weight.
So there are many reasons why people still like GPU mining.
PoW is still a solid security mechanism for blockchains and the fact the Bitcoin hasn’t moved away from it is a good indication that it is still useful.
