I did some digging into @UMX_CN, and it's backed by Avenir Group, the family office of former Huobi founder Li Lin. They operate on a compliant brokerage model, supporting direct trading of real US and Hong Kong stocks (not CFD) using USDT. Stock holdings can also be used as contract margin, resulting in high capital efficiency. The newly launched UMI "Youmi" points program is currently running a 7-day blind mining event (November 11-17), offering 3x points acceleration for transaction fees, with an unlimited 5 million pool. Those who frequently engage in cross-market trading should take advantage of this. Link https://www.(umx.com)/register?ref=DJJV1I5J
