He is really good. Also there’s this one from Ben: https://youtu.be/6TcUY2yU41w?si=D1rNpgZUn77M1592
You can use 1 wallet to mix KYC and No KYC, you just want to make sure that you’re mixing them in separate transactions.
Example:
Transaction 1 mixes your KYC UTXOs to your post mix wallet.
Transaction 2 mixes some non KYC UTXOs to your post mix wallet.
Once they’re in post-mix, you can spend them without worry, especially if they’ve been remixed a few times.
Just keep in mind that once you combine certain UTXOs in a transaction, you leave that footprint behind on chain.
As another example: if you have a no KYC source A that you don’t want to know of other UTXOs you have, it’s best to not initiate a mix by combining UTXOs from a different source with UTXOs from source A.
This is because the initial mix transaction combines them. Even if they’re not traceable after the fact, you’ve revealed that you own some UTXOs that the one source may not have known about.
