Even though the above quote is already from a couple of weeks ago, I think this is a very good idea.

I've seen a similar thing happening before bitcoin even existed. At the forum http://www.d2jsp.org/ (a forum back then for Diablo I + II) you would have 'forum gold' depending on the number of posts you made. Another way to get forum gold was to donate (with real money) to the d2jsp forum. Next to receiving forum gold, you would also receive a 'star' behind your forum-name. But the real factor which made the 'forum gold' worth a lot of money, was when people starting to use this forum gold as a currency for trading items in Diablo I + II. The more people valued the forum gold as a legit way to trade Diablo items, the more value the forum gold gained. In the end people where 'donating' a lot of money just to get forum gold so they could buy Diablo items (please note that this was about 10 years ago, I do not know whether there is still such a thing going on at d2jsp - all I know is that the person controlling the forum gold is rich as fuck).

What is interesting is that I see a lot of (possible) similarities with Digibyte currently being implemented in CS:GO and LoL. The current Digibyte gaming pay-out is obviously not a sustainable model  and therefore it is important to make it a more sustainable model. Two things which we can learn from d2jsp:

1. Make sure people can spend Digibyte on skins or whatever items in a game

2. Just as Nyo mentioned above, make Digibyte the prize money in tournaments. Clans / players will start to buy some Digibytes just to play matche for a nice amount of Digibytes.

Another option is to integrate Digibyte into a large forum for CS:GO or LoL players and be the 'forum gold' of that forum.
