a 6gpu 187mh/s on ETH uses from 820-860W from the wall. RX 580 and 570.
with 0,08$ per kWh you are getting a profit of 0,76$ a day more or less. 0,76/6 = 0,12$ per card per day even if those cards do 31,5 which is the normal performance of RX 570 and RX 580 (unless you have a crap model or you fucked it hard modding it).
so stay with me: the cheapest price for RX 570 is around 100$. provided you buy 6 that makes 600$ for the gpu cost. if you make 0.76$ per day, you need like 790 days to ROI. And this time is only for GPU ROI. You would have to also ROI the PSU, cpu, ram, mobo, risers, and all of that.
I undestand people who got into mining back in 2017 or even Q1 of 2018. But now, you have to be really, like really dumb to enter this market with current conditions and prices. It makes no fucking sense, it doesn't matter if you go for high or low efficient gpus. The profit is just laughable.
You will mostly have to hodl , paying bills from your own pocket and expect the market to go up to try to recover your investment. Let's not talk about "real profit".
So no, it's dumb to buy gpu nowadays. Don't do it.
Lol why stick on eth, this is 2019 not 2016, eth already on asic, some coin you can profitable around 400% from electric bill, you just dont know which is
always the same thing. Someone comes here, says that there is a profitable coin , and then expects the others to believe it. I've heard of "profitable" coins like the one you are saying for years. But noone knows which is it, which algo uses, which exchange works with it, if it's safe or not to mine that. If the wallet can be hacked. it doesn't appear anywhere, it's not known, it's a shitty coin (100% sure), and you have to have an special exchange that trades it for cash.
I just don't care if there is or there isn't a profitable coin right now. I'm not into mining anymore. But for the most part, all profitable coins are being mined with ASICS which makes it impossible to mine with GPU. If you are mining a coin for 400% profit, well done for you.
if you are getting 0,40$ per card, while i get 0,10, thats 400% more. But the result is that you are poor , and mining will not help you with that. So good luck with your 400% profit.
