Steem is one of the only fully functional real-world use-case coins that exists right now, while all the rest are basically pure speculation. I think Litecoin is going to have some major moves in the coming year and once Segwit gets more support will implement Lightning Network and with this will be leading the use-case charge in the crypto space. Charlie Lee is frothing at the mouth right now as he knows the only thing holding LTC back is not enough active support for Segwit.
