The following coins are my favourite and I think that they will be better coins in the future: monero, litecoin, ethereum classic, komodo, waves, dash, omisego, neo. If you consider investing in these coins and hold them for a few years, you might end up making a profit from the investment that you made. If you are actually considering short term investments: I think that ether, byteball, gnosis can make you profit within a short period of time.
