I think real value in DigiByte will appear if instead of seeking out merchants, they create their own resources to use DigiByte in.

Examples of this would be creating an eSports Betting site, where individuals could bet on big eSports competitions in Online Video Games (Dota 2, League of Legends, Call of Duty, Starcraft 2 etc). They would bet with DigiBytes.

Another would be creating their own marketplace. A site similar to Amazon, where merchants could sign up, post their goods and the whole thing would be exchanged in DigiBytes.

Just some ideas, I have plenty more if the devs are interested.
