I came across a topic asking if people can really change their name to Bitcoin for 200btc
hereand my answer was yes speaking for myself.
That very topic reminded me of an issue my brother had as he was scammed of $2000 worth of BTC but we had to track the transaction using the transaction ID on Blockchain and when tracked, we finally found the coin in a wallet containing over $600m(36754.6) worth of Bitcoin after several transactional movement.
How was the tracking done? Sometimes scammers mislead some by sending money to other people's Binance accounts or mixing them with some of the addresses belonging to Binance.
If you are sure that the money was sent directly to Binance, then your chance of recovering it is great, just be quick and contact the support team.
Other than that, perhaps if you post transaction ID , we may be able to give you more information.
and yes, Some whales (+10K BTC) post their bitcoins for commercial, tax or other reasons.
