When I deposited 10,000, everything was fine. After trading for two or three months, now when I try to withdraw my principal, they tell me there was an abnormality in the payment channel during my deposit, and they've blocked my withdrawal for 20 days. They only sent one email in the meantime. Oh, why wasn't there any abnormality when I deposited and traded? Why does it become abnormal only when I withdraw? I just want my principal back, this is really disgusting.
