There are lots of coins in Altcoin, the price is still low but has great potential in the future. Like EOS, NEO, Litecoin, RIpple, Ethereum and other coins at Altcoin. But in my opinion the more big potential among the other coins is ethereum. Because Ethereum is currently the best market in Altcoin and is the mainstay of the ICO. So I am sure that in the future Ethereum will be good and currently suitable as your investment place.
