After investing 10,0000 in BIT BUD, I was required to pay 10% personal income tax. He said that the information of bank card was wrong. After confirmation, the backstage staff changed it intentionally. After the bank card was confirmed to be normal, he also required to pay 10% margin fee to withdraw cash. He also asked to pay margin fee as soon as possible, and the account fund would be frozen within 48 hours! People with wechat can't be contacted, and the account shows abnormal status!
