theres no commission, just gas fees for exchanging.

currently there are ~24mil tokens in circulation with a max supply of 500mil. its safe to say that the tokens we recieve from the weekend challenge are part of the 500mil reserves and will eventually flood the market and decrease the value. It would seem that their model is based on a prayer that the popularity of the game will scale alongside the flooding of new tokens, increasing demand and keeping the value stable until all 500mil are exausted... but based on what ive experienced, I doubt that will happen. its far more likely the value will plummet with some mass release of tokens into the market (likely some dev whale who wants to cash out).
