Even with 0.15$/Kwh I wasn't either. I was still 'racking' in like $15 per rig after the costs. But the time I had to spend diagnosing things wasn't worth it all. Sometimes a riser would malfunction others the pool would just temporary ban my rigs for not sending in enough shares. I had GTX 1070s in all of my rigs. It's just that I could do better things with my time than diagnosing different issues every other day.
People as stupid as they are, they do not count things like that, if whattomine tell them they are making $0.15 per card they think they are making that, they are that stupid cause they might be probably negative -$0.30 per card, your hashrate is never 100%, sometimes is not even 80% real, if you have 1000mh's, your true hashrate is 25% less in the pool + risers and other things that you need to spend for everything to be functioning. The truth is, if 1 x gpu is making you less than $0.60 after electricity costs then forget mining, is time to buy coins instead.
No whats stupid is doing the same thing over expecting different results. Who in their right mind buys into crypto knowing the big players have the whole system gamed. And at any time it can be dumped 70-90%. I get it one likes to gamble but I mean come on. If you think rational investors are on board with this then good luck. But as we know people run off emotion and opinions not facts so I suppose bitcoin and the likes could goto 1mil$ per coin. But then when we see the blood in the streets we have people homeless in mass quantities. Ohh boy I can get really get behind that. Fleecing my neighbors. That makes me feel all warm inside right? This is such a joke. Buy the coins. Nothing has changed except more manipulators are in the game. Buyer beware!
