Mining just don't seem worth it. You have to factor in the cost of equipment, maintenance, electricity, deprecation of the coin mining, and all that hassle. Keep it simple and just go to a PoS coin. It's cheaper because you aren't taking up a lot of electricity, you're securing the network for the coin by actively staking; and there's basically no maintenance, all you have to do is keep the wallet open.
Best coin for this is VeriCoin. After their recent update of PoST, it's taking the PoS coin to a whole new level. Earning interest is at about 3.0 APR.
Vericoin?
Does that even exist anymore?
The whole history with Vericoin is bad bad bad.
After the hardfork story everybody lost all trust in Vericoin.
Dev team makes promises and doesn't deliver, coins keeps falling and falling.
Vericoin is the perfect example why a coin should not go POS.
