So if we add alot of these ASIC miners to the network and the hashrate doubles then, any miner but the big ASIC is going to be
screwed over by difficulty?
You are correct. GPU mining will never even come close to paying off the cards once a few hundred of these make it out the door. A few more batches and a thousand or two ASIC systems will make GPUs not even worth the electricity they cost to run. The same thing happened to CPU miners back whenh GPUs started showing up.
wahh that's what I'm afraid of - I was reading a thread that Avalon asics have already shipped and people are mining with them. If that turns out to be the case buying 2 new rigs in the last 2 weeks probably won't turn out to be the best idea T_T
