I believe it belongs to Huobi.

Take a look at the following transaction: https://blockchair.com/bitcoin/transaction/86a7f999c3c26f0cc3e9a18e028d286efc160f568797fa3846631a402df60941

In this transaction, the address you have linked spends 126 inputs to move exactly 1,000 BTC to the following address: https://blockchair.com/bitcoin/address/1BQeVsS9YfAuwRLjVowzvVKcjZx6onmEbg

That address has a pattern of receiving a single large value input, and then makes a transaction which spends that input to pay out a small amount to a number of address, and deposit the majority as change to another address. For example:

This transaction spends 1000 BTC and sends 984 BTC to 1EDK4M7gcAD5fW5sngxTty54cEvsG7me2k.

This transaction spends 1000 BTC sends 972 BTC to 1FKXTigFBHU3rSdQLecBuw72xBD2QZN95S.

This transaction spends 500 BTC sends 438 BTC to 13aqS5nmnmK25yhhJqY8eU4kds8LnrPG4W.

Those three high value change address are all part of the same wallet which is known to belong to Huobi: https://www.walletexplorer.com/wallet/e80581544df795d8?from_address=1BQeVsS9YfAuwRLjVowzvVKcjZx6onmEbg

I've never had a Huobi account. But I did have a crypto.com account. They are based in Hong Kong so that address may belongs to them. Let me see if I can get in touch with them.
