are other ethereum clone affected by this shitty diff scheme? i hope not
I don't think so. Its sole purpose as far as I understand is to act as a transition from PoW to PoS. I'm not sure why they didn't decrese the blockreward instead.
So no replacement of Ethereum once it becomes extremely hard on GPU mining? What about Dash?
I'm planning to purchase GPU of $200-$300 and then buy more time-to-time. But it'd be pretty bad to see once ether mining becomes useless. GPU miners will have to explore some sort of replacement.
Dash is x11 and there are x11 ASICs which means it's a bad choice for GPU mining.
