Well, I only invest to coins that have good background with respectable devs and should be active to communicate to its investors and community. If I remembered it correctly, I invested heavily on Waves last year. I participated in their signature bounty, bought some of their coins in the ICO phase and bought more when people dumped it hard post ICO. I gained so much from that coin and still holding some more because I see more upside potential to it in the coming months.

As of the moment, I'm gathering some of my money to invest it to Enjin (see my signature?  ). I'm a gamer myself and my thoughts on what a coin for games should be aligns with what Enjin is trying to bring into the table. Fundamentally, this coin will be big in the future.
