I've been trading new kind of coins and I just lost good amount of money. I also prefer well established coins than the newly introduced one.  I just buy bitcoin, etherium, xrp and the likes. This is more surer than new coins, the potential of this coins is really good knowing that it reach a high peak from the last years. The future is bright for the well established coins. I also like this coins since I can store them all in one wallet called Hodler which is the only full open source multiwallet.
