My advice is dont bother. You will never achieve return on investment, even the electricity you will use. The markets are building up for a huge crash (sub $3000 bitcoin) its formed a right triangle, thats a very bad sign.
Ive been mining with my old gaming hardware since December 2017, and since the markets have crashed lately I now have spent more on electricity than I have in crypto. I have $160 CAD in crypto mining on 3 cards (HD 6950, R9 270X, and RX 580) 9 months mining and only $0.06/kWhr electricity and I still didnt manage to pay for it. The only way I can see making any kind of profit in this enviroment is with ASICS. GPU Mining is dead.
"only way to make money is with ASIC"
"gpu mining is dead"
you obviously dont know what youre talking about
most miners who started summer 2017 or earlier would have made ROI by now or very close, unless they overpaid for their gear
mining profitability is shit compared to when i started last year, but considering i already made roi, i am still profitable.
ASICs are a great way to destroy mining. ask the antminer D3 and equihash crowd
