So I'm thinking of cashing in some of my BTC, to the tune of $900 and buying 4x RX 560 4GB cards to mine Monero, or even possibly Ethereum (or ethereum classic depending on whichever is a better investment...) Each card should get a base hash rate of 350h/s.
Mining calc tells me that it's $80, with current difficulty and price, a month, on the cards alone (mining Monero).
So is it a good idea to buy them and try my luck with gpu mining or keep the bitcoin and hope the price keeps going up?
