i wish to have my old gpu gear back and mining altcoin like in the good old days, i'm not too much in the asic miners, they are so limited and help centralization, i prefer freedom and decentralization
and gpu can mine everything the fact that they are no as a efficient on sh256 isn't a problem if you can mine something else and convert in bitcoin, the result is the same
Asics are all that keep big corporations from being the only BTC miners. Yes the profit is not as big as we want. We always want more.
I think even if after halving the little guys are forced out there will still we some decentralization. Not as much as we want but still some. I don't think we will ever see a pool with 51 percent again.
Hurting BTC just is not in anyone's best interest. Even if 3 or 4 big companies only mining most likely they don't want hurt their business.
