So I have a 2/3 multisig cold wallet that I sent my Bitcoin to a regular Segwit wallet I created on Sparrow... When the mixing finishes, can I mix the UTXOs back to the 2/3 multisig cold wallet (using unused addresses) or would that ruin the privacy gains?

It will harm the privacy gains to recombine mixed UTXOs

Thanks for the info... My concern is about the multisig script... If I'm using the same multisig cold wallet, wouldn't it have the same multisig script for the UTXOs prior and after the mix? And could that somehow tie back to the pre-mixed UTXOs?

The multisig script is not unique to you, but it’s definitely something identifiable. If you go in from 4-of-7 multisig and out to 4-of-7 segwit multisig, there’s just not that many people using 4-of-7 segwit multisig so you might stand out in a chain analysis. But it wouldn’t be deterministic still

At least that’s how I understand it, definitely find someone more technical than me before you take my word for it

Really appreciate the insight 🫂🫂

Your utxos are recognizable as mixed one way or another. Next time you spend these utxos from multisig it will also be visible that multisig was utilized but that doesn't compromise the initial privacy gained by the coinjoin. Maybe gives a strong indicator that they're spent from private cold storage, exchanges or companies have larger utxos under multisig.

I'd say your good with mixed and multisigged coins.

Best practice (but yes pain in the ass) is to mix them all to a new cold wallet.

What if I changed the order of the cold wallets but still use the same ones? Would that help?

So my Whirlpool mixes almost have 10 mixes and wanted to get more feedback from any multisig experts...

Long story short: 2/3 cold wallet, bitcoin sent to SegWit wallet created through Sparrow... Can I mix back to the same 2/3 cold wallet (using unused addresses) or will the 2/3 script give away privacy gains?
