Put a cork in it yourself. GAW has promised to make XPY worth $20 on Paybase for using XPY. That isn't the same as XPY being worth $20 on a random exchange. Logically if you can use it for $20 on Paybase, it would be worth slightly less on outside exchanges. You can bet all you want, it doesn't mean anything. I've bet with the XPY I currently own. I don't need $20/XPY to win large.

Would you like to wager on whether or not paybase will allow a withdrawal of sold XPY in BTC or fiat on the 29th? You really think that he is going to payout 20usd on the 29th?
