Big movement forward in general, however, the BIG question is how do you deal with fiat in “banks”? The only downside I see is being a seller and receiving “dirty fiat”. And this happened to various people I know (many times with Revolut) -> flags, delays, explanations, investigations, even freeze.
I got the benefit of zero trust, privacy, on one side. On the other “fiat side” nothing changes and still has same downsides (when receiving fiat -> counterparty risk). To solve the fiat “freezing/investigation” downside there’s honestly just one option (it costs POW - time, effort, physical location, etc..) and that is physical P2P via @vexl 😎 . With digital fiat involved it is just a partial solution and it is important to count with “digital fiat” drawbacks.
