Mine your ETH while you can and quit complaining. There are many events now in motion that will make mining ETH all but impossible a year from now.
Public release of ASICs coming at the end of July, quite a few were sold at $800, all of these will come online basically all at once. This does not even include all the secret ASICs running currently.
Fools continue to buy and build GPU based rigs, not realizing they will never ROI, at least not with Ethereum, Zcash, or any of the other algos that Bitmain has developed an ASIC for.
With the upcoming transition to POS, the mining reward for ETH will be reduced once again, this time going from 3 ETH per block down to .6 ETH per block. Eventually mining reward will go away completely.
Once this finally does phase out, the remaining coins and algos that can still be GPU mined without ASIC competition will be very few and all those GPUs will need to point somewhere. The days of easy gains and paying off your hardware investment in a few months are over and will not be returning anytime soon, if ever.
Just be glad you got to participate while you could, but from here on out only the big boys with multi-million dollar plus farms consisting of the latest hardware coupled with private mining software and cheap electric contracts of a few cents per KWh will be able to make a go of it. You may have another year to play around with ETH and a few other profitable coins, but I really do not foresee profitable home mining continuing much past that.
None of which you say are true, except the block reward for ETH at a later point. Not anytime soon. ROI for GPUs is at 8 months at current prices. You are a fool to think prices will stay the same. Prices always go up over time. The 8 month ROI will eventually become a month month ROI as the investments go up in price. I don't think many GPU miners mine ETH since January - ETH was taken over 50% by Bitmain in December. Its all about RavenCoin now a days anyways.
