I won $50,000 and withdrew via Bitcoin and it was approved. I got 8 deposits and then my withdrawal was cancelled with no explanation. I attempted a second withdrawal for the remaining money and it sat in review for 10 days. I called and chatted online with customer service and asked several times why my initial withdrawal was cancelled and no one ever gave me an answer and just kept saying that my current withdrawal would be approved shortly. I have since cancelled the withdrawal and started a new one. No one in customer service has been helpful.
