If you're technically oriented, and feel safe that your nostr private key also unlocks your funds, then yes, coinos is a good option.
Our experience is that the ability to recover your account by email -- combined with a 2FA device -- is the right choice for many users.
Without that recovery option.. if you paste your nsec into the wrong app or lose it, then you lose your funds.
Again, for technical users this might be an appropriate risk.
It does not rely on Nostr, has login/password and a 6-digit pin for payments. A fake emai suggested abovel is even worse.
I see what you are saying about the fake email. I only hold small funds for zapping as it is custodial. Yes, I have not tried CoinOS. Does it have NWC? As I needed a quick way to get NWC. I already run my one lightning node and have my own BTCpayserver on my Sovran Pro.
Yes. Also BTC and Liquid BTC
Yes, for technical users who are likely to set up "login/password and a 6-digit pin for payments" -- all good. But for normies, they won't set it up, they will only use their nsec, and many will lose funds because of this.
Plus, I can open direct channel to Coinos for free lightning payments back and forth.
