My point about about Asics not killing GPU mining and Vitalik "Super out of touch" Buterin killing GPU mining is this...
I acknowledge I might have some math errors and not all cards mining ETH are RX 570/580 cards and I am simplifying things a bit. But I don't think my logic is flawed. I REALLY hope it is. So please... argue...
ETH currently has 266,000 GH. So that is equivalent of 8,866,666 RX 570/580 cards. Imagine if they went PoS. The current XMR network (500 MH or so) has about the what would equal 62,500 570/580 cards on it. So if let's say only 200,000 of those ETH cards when to XMR... XMR would be much less profitable to mine and you would still have 8,666,666 cards to still spread over other coins...
Continue this exercise with the next coin... and the next... and the next...
I realize that some miners will stay on ETH as the block reward will still be 0.6 ETH... so 20%... 1,773,333 570/580 cards.
I dont get what u mean by out of touch. Innovation occurs. Things change. Cant do much about it.
GPU is the past. Horses were used in the past. Then, cars came. The problem with mining is that it is getting harder to breakeven these days.
I understand your pain. Buyers gotta hope no competitor comes up with a similar asic.
