BIP47 is great but solves a different problem, still need to use coinjoin.

Upgrade to BIP-351 for a modern payment code 😉

Sounds like you wanna double dip. Bitcoins value and privacy. Bitcoin was never made to be private while Monero's(XMR) privacy technology is similar to CoinJoin, in that it uses ring signatures to mix the spender's signature with the signatures of other users to make tracing addresses nearly impossible... What are your thoughts on XMR, other than "its not bitcoin"?
