On all the sites I play on, I only made the minimum deposit required by the room to be able to link my bank account to the site, and I never made any more deposits.
I've already made a lot of withdrawals in all the rooms I play, the only room I haven't been able to withdraw from is WPT Global, they still haven't approved the documentation I sent, I don't know why.
But I don't care because I'm no longer playing in that room, despite having a Bankroll of $394.00, the only room that blocked my withdrawal was Pokerstars in my last order, and it was precisely at the time that they stopped offering the Cardschat freerolls.
Pokerstars sent me an email message claiming that I should play more of their tournaments to be able to release the withdrawal, I currently have a BR of $77.00, but I haven't played anything in this room.
