Go ahead and mine Ethereum, it's the most profitable right now.
The catch is, your GPUs must have more than 2GB of VRAM.
Right now Ethereum is low in price, but still is the best altcoin to mine ^.^
not sure to understand how it can be "low in price" and "profitable" at the same time...
You are right, i meant to say that Eth is the most promising altcoin out there, it has the biggest market volume of all.
