Well guys... sold my small business (restaurant), bought a shitload of GPUs.. and now I realize I may not know what the fuck I'm doing. I've got almost 70 cards running (mix of 1070s and 1060s, mostly 1070) mining rvn, getting like 1,500 a day or something like that. Overall at current prices, making like $430 a week before power. Which isn't shit. I realize I can go nicehash and make more probably but I'd be making maybe $600-$650 with nicehash or ethereum or zcash (probably a bit less with zcash at current prices).. My point is, is this the best way to go about it? Mining something speculative, or mining the most profitable coin at the time and exchanging to speculation? I need to liquidate at least some of my monthly earning to get by, but either way, it's a meager existence, and eventually, these cards will crap out despite my best efforts to keep them running at 65 Celsius, and I'll have nothing. Does anyone have any advice for me? Is it really true that 70 fucking Nvidia GPUs can only earn you round-a-bout 2k-2.4k a month after power?? Did I just screw myself??
