Now my main aim of creating this thread is that a friend asked me to send my BTC wallet address so that he can send me Bitcoin for me to sell it and send him fiat, but I am curious because of my safety since I don't know the source of his BTC if he got it by scamming someone. A thought cam to me that this might be a risky transaction and I don't want to send him my exchange wallet address.
My first question was supposed to how do you know the person but luckily for you it’s your friend and you already know the person so why are you scared when you personally can trace the friend if anything goes wrong. But seriously this is just like traditional fiat transactions which if you’re not comfortable with the person you’re dealing with, you don’t actually proceed with the transaction.
Now general one of the easiest way to maintain privacy with bitcoin is using different addresses for every different transactions and make sure this addresses do not interact with each other. So for your own case I will simply say you just use a different address and make sure while selling off everything from this address it is on DEX or use coinjoin/mixers, this way the UTXO never gets any traction with your other addresses linked to your identity
