If you mix in whirlpool every mix deeper you go increases the obfuscation exponentially so after 5 mixes (each mix is 5 participants) you get 3125 different addresses that could be you. Another mix gets you 5^6 so 15,625. So I’d say the sweet spot for long term storage is over 5 mixes in whirlpool to be sure they’ll never know.

I would use Sparrow wallet on desktop or Mac and connect to a full node that you own to mix with. Sparrow wallet has fantastic whirlpool integration, better than Samourai’s own wallet imo. Make sure to pick the right pool size so you don’t pay too large a fee, there are good guides online that explain how it all works.

Just be aware that fundamentally when you’re mixing in whirlpool it’s a hot wallet because the wallet needs to be able move the bitcoin. You need to leave this computer on all the time and it will just mix for you 24/7. Just explaining what I do. You can tell the mixing wallet in sparrow to automatically withdraw to a public key address you specify after a certain number of mixes so I just see transactions trickle into my cold storage over the weeks/months it takes to mix my bitcoin.

You can password lock the hot wallet too and it will keep mixing and stay connected to your full node so that’s good, password protected hot wallet.

You don’t need to mix a lot of bitcoin either. There is a 100k sat pool, try sending over like 750k sats and if you mix in that pool you’ll end up with 7 100k sat utxos mixing.

This disadvantages of whirlpool are the small round sizes (5 inputs and 5 outputs) and unmixable change. Wasabi coinjoins are more efficient and more private since they have much larger rounds and eliminate the problem of traceable change. Here's a side by side list of features:

You don’t have to tell me, I’ve used both and I much prefer Whirlpool.

Why do you prefer Whirlpool?

A big factor for me is just understanding the entire model a bit better than I understand Wasabi. I’m going to spend more time with Wasabi this year to try and get a better grasp of it. I like the fee system of whirlpool where you can get increased mix depth for free (just requires waiting longer) but yeah, tbh I should learn more about Wasabi and I will.
