#出金安全 I don't know when this cryptocurrency can be traded normally like securities and futures. When I read the stories of the square, I sometimes see people who use U and their cards are frozen by risk control. Although there is no specific law that prohibits it, everyone with a discerning eye knows that this is a gray industry. I hope it will stand in the light one day. It seems that most people who use U use a foreign exchange card, but it still feels quite troublesome. When can UnionPay be used directly without having to change it back and forth? Wait for the light to come, and get up at dawn.
