Better study things first in trading coins because trading is not just a joke joke matter,you are going to put your money into it, taking the risk of putting money into something you do not know what will be the result of that.

But to give you a simple thing, it is right to start trading with small amount since you are just like making some experiment and trying to work things out.  Secondly, look for good things, like if you trade some alt coin consider their long-ness in the industry because you might go to wrong one not knowing that they will just dump your money. Just always secure things. It is better to be wise that be wised by others.
