Altcom's difficulty is currently low. The devs are active and theres big plans for the coin.
Check out their ANN thread.
Nice to see right after you say that the coin is on top of whattomine as most profitable. If you have been mining that for a few days then you got are probably making a nice little return right now.
It's still in the early phases. So I think it's a good time to mine it.
There should be a platform released in a few months here. So I'd bet the early birds will see a bit of gains.
