This might just be the newbie in me talking, but I wasn't planing to pigeon hole myself to one mining strategy... In my newbie view, I think Ethereum has a lot of future potential, so I'd be apt to sit on Ethereum for a long time, but from a current value standpoint, I can make more than double the US dollar value mining ZClassic with the same rig as I can Ethereum... My logic on that is if I'm only making $15 / day mining Ethereum, but the same rig will yield $38 / day in ZClassic, doesn't it make more sense to mine ZClassic, exchange it into Ethereum and sit on the Ethereum longer term? I didn't think exchange rates would eat up that large of a profit gap between coins... Again, that may just be the newbie in me talking .
