According to Mars Finance, X user @thcaroline2233 revealed that approximately 6.2 million USD in their account on the on-chain US stock trading platform Mystonks cannot be withdrawn. The user stated that they had previously recharged over 7 million USD to the platform through Binance, and successfully withdrew a total of approximately 1.18 million USD on July 22, August 11, and August 12. However, when they later applied to withdraw 3.6 million USD, 2.6 million USD, and 230,000 USD, the platform requested additional materials on the grounds of 'triggering risk control.' The user claims that after submitting the materials, they did not receive any substantive response, and when mentioning the withdrawal issue in the official Telegram group, they were muted, with no progress made in communication with the platform's customer service or via email. They also mentioned that a friend has informed them that the related funds may have been dispersed and transferred. Currently, the user has made their recharge and withdrawal addresses, as well as some transaction records, public, and is calling on other investors to be wary of the potential risks of the platform. The Mystonks platform has not yet made any public response to this matter.
