Investors lost all the investment funds they deposited on the Mounto Investment Platform, totaling $23,021 (equivalent to 33,663,703 KRW), in an instant on September 26th. The broker requested that investors deposit more funds, stating that if they invest more than their current trading account balance in the Silver account, they can upgrade to the Gold account and recover their losses. They also mentioned that using AI Level 3 can prevent stop-outs. In response to this request, on September 13th, the investor deposited an additional $7,771 as investment funds. The profits were gradually increasing until September 19th when the trading account balance was $36,296. However, after executing the broker-recommended positions as "sell" on September 19th and 20th, the margin level started to rapidly decline. As a result, the trades recommended by the broker resulted in significant losses instead of the expected profits, causing the investor to lose all their investment funds in an instant on September 26th. The current account balance as of September 26th is $0, down from $36,296 on September 19th, and the Total Profit is -$52,319.
