I unfortunately do not have a Mining Rig to mine anything, else it would be something I'd think about. and I am scared to try cloud mining i hear bad things about it. right now I am mostly invested into Clam and just on-site investing it on JD looking for the right moment to trade for BTC and wait for Clam to drop and rebuy back in is what I was thinking at least until I build something self sufficient worthy
I'd say thats fine for now, Just-dice.com is a great site and should bring you profit from your investment and Clams are good coins also, its better to stick with something you know then trying something you know nothing about. Trading alt requires knowledge as to which one looks promising based on various factors, you can try small and learn with trial and error but its hard to pick the right ones as there are so many shit coins around.
