Any altcoin you go for is good. We have Ethereum Classic, Ripple, Monero, Zcash, Bitcoin Cash, NEO (one of the best), Litecoin and many more of them. But anyone of them you pick interest in, be sure to make a quick research about it so you can know how it works and understand it better. Dont just jump into it without knowing anything about. Try to follow up with the news and also learn how to read the chart yourself.
