So you think Betcoin is unethical with their casino but ethical with their poker?  That's a REALLY large leap in logic.  Especially for a site that's been quite unethical with their poker room in the past.

Also, the WTN doesn't 'trust' Betcoin.  It's a std skin deal.  When a player buys into a tournament, Betcoin pays that amount to the network (which comes from the player's account) and if a player on the skin wins, the network pays the skin for them to cover the player's new balance.
