I'm still using nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv and mint.minibits.cash.

Yes, it is beta and buggy, but it's the only e-cash dev I trust, so I'm sticking with the devil I know.

I have also had good experiences with nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm and Phoenix, so I keep using them, too, and I used nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 for a while and liked it.

I actually am okay with some bugs, if the developers seem to take them seriously, attempt to prevent them, and handle them in a swift and professional manner. Continuous improvement in the quality, from iteration to iteration.

Not financial advice, but my personal opinion.
