Would it be that absurd to simply change the name of this coin?
Something along the lines of GameTokens? No idea why the entire community continued the "coin" craze when it comes to naming schemes.
We could do a small brainstorm get a few names, then hold a poll to vote on one of them.
My theory is that "Coin" has stuck partly because of laziness, partly to try and snag some brand recognition from BitCoin, and partially because when you think "Coin" you think money, something that has real value. Th eonly reason I'd want to shy away from "token" is that by definition a token meant to be valueless stand-in for money.
To be blunt, "Coin" is sexy.
Though I'd be totally down to just start calling this coin GP, as a nod to classic RPGs or something like that.
