For current Bitcoin holders, we first possess on-chain sats, then convert a small portion of those into Lightning Network sats, and subsequently turn a small portion of the Lightning Network sats into ecash sats.
For new users who are not yet Bitcoin holders, they might first acquire ecash sats. Once they accumulate enough, they can have self-custodial Lightning Network sats, and as the amount grows further, they can then own their own on-chain sats.
The order of acquiring sats is potentially reversed for new users compared to existing Bitcoin holders. nostr:note1wet48xvad8uwx0zhuf05lamcmfnxt7dmqhlpaxhakmmr2vqfpj7s92ylgl
