I found this coin through the league of legends promotion.  Getting free DBG for playing has now caused me to buy a bunch more as well!

I think this promotion has very good potential, but I think the referral program for it could be improved to really reward people for referring many users.

I think that the current system of getting 5000 free DBG if you refer 3 friends should be changed to add a 10% (or something) payment for all coins earned by your referrals.

This would incentivize 'famous' league of legends players to refer their fanbase, which could result in some massive growth of the userbase.  Imagine if one of the top LoL streamers started promoting digibyte in their stream to tens of thousands of their viewers?  They could probably get thousands of people to sign up.
