Does anyone have any experience using Whirlpool to mix UTXO’s on air gapped wallets visible on a watch only basis on Sparrow? I’m trying to understand how the process goes for creating the mixing transactions and signing them with the Cold Card so they can be broadcast. Or is it better for privacy to initially move the UTXO’s to a new hot wallet that has never had coins on it, and then post-mix have them go to a clean hardware wallet address that you’ve never sent any KYC Sats to? Thanks.
