Did the business partner try and contact bybit. This is not a lost cause. Bybit should be able to recover this.

How my friend lost $50,000 USDT on binance.
About a month ago, my friend was trying to withdraw USDT worth $50,000 from his Binance spot wallet to his business partner’s Bybit wallet , his business partner provided him with a wallet address of BEP20 network.
In the process of withdrawing/transferring the $50,000 worth of USDT my friend mistakenly tapped on opBNB network instead of BEP20 network and proceeded with the withdrawal.
The USDT never reflected on my friend business partner’s Bybit wallet till date.

Lesson: Always verify and confirm wallet addresses and its corresponding networks before proceeding with withdrawal
