Biztranex blocked my arbitrage withdrawals and demanded another deposit

I was buying cryptocurrency on other exchanges and transferring it to Biztranex because the platform displayed higher selling prices. The balances moved normally between assets inside the account, making the arbitrage activity appear genuine.

The problem began when I tried to withdraw. Although the dashboard still showed my money, Biztranex stopped external withdrawals and asked me to make another deposit before the funds could be released.

Internal balance movements do not prove that an exchange holds real assets. Once a platform requires fresh money to unlock an existing balance, I would stop immediately rather than increase the loss.
