Still worth buying GPUs? With Ethereum mining getting tough. Can we hope for another profitable coin?
IMO the only reason to risk buying new gear (or even not-super-cheap USED gear) for mining Ethereum with is *IF* you were going to buy it anyway for some OTHER use, and plan to mine Ethereum just to help pay PART of the cost of the gear.
Technically, planning to "resell" the gear might count, but I'd hate to COUNT on that with the rapidly declining profitability of Ethereum mining.
I have the high electricity price of $0.23/kWh. So I will not buy graphics now to mine. The difficulty is too high.
