Trading is double sided, instead of being rich on it you may lose because not all altcoins is promising they may not last for a long run and you need a big capital if you want a bigger profits. Well the posted above is right, if you know how to manage your investment then you can be successful.
I do a lot of trading, but sometimes it seems as though it would be just as good to buy and hold. If the price goes up and you sell to buy back later, sometimes the price just keeps going up and you miss out on those gains.
