Tier 1: Custodial

Example: Wallet of Satoshi For who: doesn't really care about self sovereignty, wants an easy solution, wants convenience. Introduce first time users, who don't show any interest in trying to learn more. keep an open door in case they wanna learn later, you can upgrade to tier 2. For what: pocket change, daily spending

Tier 2: Semi non custodial

Example: phoenix For who: someone who is interested in self sovereignty and wants to learn more about it. Someone who wants to learn how btc-ln works, at least superficially. Someone who is willing to give up some convenience for a bit more control. For what: Daily spending

Tier 3: Fully non custodial

Example: Bitcoin core+LND+Zeus For who: someone who wants to go down the rabit hole For what: for being reckless
