Hey, @BTCsessions please tell me, what you think of this :
Because Coinjoin are expensive (and almost illegal...) do you consider this "buying path" to be somewhat "private" ? :
Buy (on CEX) -> withdraw via Lightning -> swap to Liquid (viva AQUA wallet !! ) -> send to Sideswap -> Peg-out to Cold Storage (using a new adress)
Giving that Lightning transfer may be hard to track, and that Liquid transaction are (in theory?) "anonymus" (blinded), I assume this is kinda equivalent to a coinjoin to "mix you trail" from CEX to cold storage.
