And on the cryptofantasysports site, as well as the poker site, you should make it very clear to players buying in that this is a currency so its subject to fluctuation, so they clearly understand that holding it is exposing them to market volatility.  most of these people have probably never traded between currencies even.  they don't have experience with this.  so they have to be educated a bit.  so they understand that if they want to avoid exposure they should minimize their time holding.  You have to explain this to them and make it easy to get in and out, so they can decide what they want to do.  and make it cheap to do.  otherwise this one little detail could, and i'm serious, affect your business.
