Ethereum.
It's switching to proof of stake soon, and it is the biggest altcoin at the moment.
Maybe look into Peercoin? It's almost dead like Litecoin and Dogecoin but used to be really popular back in the earlier days.
I wouldn't be surprised at all if PPC got revived soon as well like LTC and DOGE.
