Gaming Coins are an interesting space as the gaming industry is currently booming with the growing following of e-Sports. DGB seems to be a decent long-term investment, but the big speculation surrounding their Citi presentation created the boom in popularity, just to fall right back down after they lost the competition. It ill be interesting to see if DGB can gain a following again, but that could take another few months before they get going with Minecraft and League of Legends, etc.
