I guess now the bad got badder, cryptonight asics are about to be released to the public and it looks like this thread might come to be the truth in 2018 and here I thought cryptonight would save all gpu miners. I can't believe I will be right again. I wished i could be wrong for once but I guess my experience within the crypto community since 2008 tells otherwise.
Why cryptonight Asics will kill gpu mining?
A LOT of hashrate of cryptonight are botnets, and CPUs
If cryptonight is not worth anymore, hackers will stop to use botnets, and people will turn off the CPUs to mine
In my opinion, the only real danger is Asic for ETHASH, because most of GPUs are mining ETH
And to kill ETHASH the performance should be HUGE
