Manually Set Cost Base?

My coins were purchased from a friend of mine, so I am not able to import the transaction. They were simply sent to me into my binance account.

For taxes, I can prove the cost base, so I just want to manually enter a cost base for the starting amounts in my BTC and USDT wallets.

Is this possible?

Thanks!

Yes, you can edit the received transactions’ cost bases from the transactions page using the dropdown next to the transactions.
