The thing I can't stress enough is that only amounts are hidden. It is trivial to see sender and receiver in Liquid so can easily be traced in and followed the whole way out. Waiting and breaking it u...
Thanks for clarifying.. Seems like LN -> LN -> loop out will give better privacy. One could let a few sats accumulate on LN, then send to liquid for "semi" cold storage before sending to final CS onchain... LN -> LN -> LQ should sufficiently break the link imo.
