A 48+ minutes tutorial?! Two questions right off: is it no-KYC? And is it non-custodial? If not...

As a Blink wallet user, I can tell you that it is non-KYC, and while it is custodial, it's open source, so anyone can review its code. So, IMO, it's a great bridge wallet for on-chain and Lightning sats, and a great place to hold some sats for spending, but not a great wallet for holding large amounts for a long time.
