I think that trade altcoins is quite a profitable, but it is very risky. if you do not know how to trade, you better not to contact them.
Yes for trading you need to have skills and patience. I know a friend he made a lot of money with investing in altcoins etc. So trading in altcoins is truly profitable if you know how it works.
If you haven't did trading before you need to contact one of your friends or your collegas who did that before unless you want to lose your money go ahead xD.
