I see the ideal exchanger as follows:
Select the exchange direction
BTC - USDT (solana)
Enter your BTC wallet address
Then there are 2 options: AML verification was successful, continue the exchange or AML verification was not passed, we cannot perform the exchange
That would be great but it remains a dream for now. Many times, not even the exchange knows why certain coins aren't allowed. I am sure they receive the most basic of feedback from their AML and blockchain analysis partners.
I don't know how to say this, but for example, you think that your coins are dirty, but when you exchange them, they turn out to be clean.
This often happens, but you shouldn't hope that it will always be like this. Sometimes you need to test theory in practice.
