My unsolicited opinion, offered in the spirit of friendly cooperation:

After having extensively studied the history of US financial crackdowns and repression, my conclusion is Coinjoins of any kind are not worth the downstream risk.

If you coinjoin, you are putting yourself in a bucket earmarked for regulatory scrutiny. They WILL be looking at you at some point, in the same way they look at Belize bank accounts, Panama visa cards, and so on.

Better to be a nameless, faceless, clueless bitcoin speculator who lost everything along the way. They understand that, and fits in with their preferred narrative.
