Thousands of traders across Africa have been left reeling after an online trading platform collapsed, vanishing with their money, in the millions.

Crypto Bridge Exchange (CBEX), the company at the centre of the scandal, is accused of operating a Ponzi scheme that promised investors a 100 percent return within 30 days.

When users attempted to withdraw their money, the company failed to honor requests and abruptly shut down its physical offices, amid mounting complaints.

According to investigations, the trading company presented itself as a legitimate digital asset trading platform under various names, including ST Technologies International Ltd, and Smart Treasure/Super Technology.
