This has really been on my mind quite a bit recently as it really feels as if we are shooting ourselves in the foot! I don't know what the solution is though and what we need to watch for to establish wether or not profits will ever increase again.
It's already getting VERY close (few less BTC/Mh/Day) will mean power consumption vs. BTC earned will make this unprofitable and I really wonder if we will ever see an increase or if we are in the last vestiges of mining...
I sure hope not! Please someone give us hope lol.
