Is BTCC Global legit? In this May, a netizen pulled me into a group,in which a teacher gave recommendations everyday.When I made investments in index and gold,I was deceived with my account abnormal and liquidated,thus having no access to withdrawal.Heavy losses caused by Ming zhe,Wu ya,Han yi and Hong tao’s instructions on nonferrous metal and severe pollution,as well as unavailable withdrawal.
