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.
