I do not understand why you think that trading altcoins is somewhat safer than trading bitcoin, altcoins have lower volume, a smaller user base, they are not used for anything other than speculating with them and they are even more volatile, in my opinion you have it backwards, you need at first to try to trade bitcoin and if you are unable to get profits in the bitcoin market then it is going to be impossible for you to get them in the altcoin market which is even more difficult to trade.

Some may say that is a good idea to invest in icos or ieos but those coins are even more difficult to predict because you do not really know what you're going to get.
