I personally like MomaCoin, they have solid Japanese community, who tends to more patient and loyal, so that sudden price drops wouldn't hurt that much.
Yes, MonaCoin is very promising and I think it's a good buy. It's one in my list of 20 coins I've been monitoring over the past 3 months and that includes Bitcoin, of course, Ethereum, Bitcoin Cash, Litecoin, Monero, Waves, and LEOcoin among the few.
