As I said many times on nostr and also in one of my guides: ecash should be used only in specific use cases. If you want tot use ecash you must put some trust in the mint, because is no more than a gift card. Fedimint is a trick, fooling people to give the trust to many. So now instead of trusting somebody you know, you will have to trust multiple dudes that you don't know.
Cashu should be used in small communities. Example Cuba have some communities where they created a local mint just for their users and merchants. Because in their case cashu is a perfect way to transact with sats.
