It is right, trading has benefits, but only for those people, who have a knowledge and experience of trading. Because when i started than i didn't know very well about it, so it couldn't give me a chance to make money, but after 1 year, i know, how to trade. Well, main thing is that you should have patience and consecrate your trading, and daily check it our, which coin you have bought.
yes that is right to say that knowledge about trading is too much important, there is too much risk in trading if you have no knowledge about trading. therefore if you are going to investing your money in alt coin or some where else first you need to get some good knowledge about it.
