On November 11, 67, I traded BTC and made a profit of US$ 23,xxx. I was about to sell, but the system was hanging. When I contacted them, they told me to wait. The IP signal of the trading platform was down, which made me lose confidence. I decided to sell immediately when the system is operational on the 12th and have been monitoring until today, the 13th. They replied that they will close the account and refund the principal, which is not fair and irresponsible. They cited the IP signal and the new provider as reasons. The customers are not at fault and cannot be trusted anymore.
