Okay. A thing that's been on my mind when comparing fedimint and Liquid, (besides the auditability problem) is distribution of custodians. When the Fedi guys talk, they make it sound like a Fedimint's 'guardians' will be trusted members of a community, so likely all in one jurisdiction (and vulnerable to nation state attacks/pressure). They COULD be distributed across different countries, but trust doesn't scale distance-wise well. You could substitute reputation and skin-in-the-game for trust, and then you recreate Liquid's federation.
So auditability? Can't be as good as Liquid.
Resistance to nation-states?
Best case scenario? It's AS good as Liquid.
Most fedimints will probably be worse, all keys in one jurisdiction.
(Of course the near perfect privacy of ecash is FAR superior to Confidential Transactions which only hide amount and asset type.)
Because of this, I will definitely be using ecash due to it being the easiest way to privately use Bitcoin.
