right, I always thought the cost of DDR5 memory was the limiting factor here at least for Eth
Is limiting the factor x profit, from the words of charlie lee himself, "nothing can avoid to asic it if a coin becomes so popular" and you trolls should always remember that. As long as gpu mining a coin is at the beginning then nothing to worry about asics, ethash and equihash are popular, so gameover to gpus.
Right now ethash network is fully protected, nobody can have 51% total hashrate, with asics that can be true, right now eth hashrate is totally decentralized, btc hashrate is mostly centralized and that is bad.
By the way, this is a good thing, this will stop retailers selling rx 580 for $1000 and the way things are, soon a rx $580 will be $3000 or even $5000 because there is no stopping to stupidity.
As soon as asics hit equihash and ethash then gpus from $1000 will be sold for $100 and then $50. Gamers will have all the gpus they would ever need or wanted hehe
