Ju.com froze my profitable account and confiscated the remaining deposit

I completed KYC and traded on Ju.com for several months. Early withdrawals worked, which gave me confidence that the exchange was functioning normally.

During a later trade, a notification said my account had been frozen. Moments later I was logged out, and support informed me that the ban was permanent, the deposit had been confiscated, and no appeal was available.

The platform went from normal operation to complete account loss without a transparent explanation I could challenge.
