I installed the app, presented my ID, and opened an account. Deposit money into your personal account several times according to the instructions of customer service. I made a profit on dozens of trades. When I requested a full withdrawal, I was asked to pay a 20% service fee within 3 days. Since I can't pay, I asked them to stop the withdrawal, but it has already been approved. If you don't pay within 3 days, it will be frozen. The transaction was carried out as instructed by Hank, who calls himself Korean, on LINE. The total amount of damage deposited was 9.5 million yen.
