If the address 3QsGsAXQ4rqRNvh5pEW55hf3F9PEyb7rVq is not owned by Huobi, then it is certainly closely linked with them. Do they own or hold large stakes in any subsidiary exchanges, wallets, payment processors, etc?
Crypto.com offering a "deposit service" in which customers can deposit coin and earn interest. Huobi has what appears to be a peer-to-peer collateralized lending platform. If the OP is correct about his address belonging to crypto.com, it is possible they are using some of their deposits to fund loans on Huobi's platform.
