Self custody is a spectrum not absolute. That is my point.
1 sat on a primal wallet is bitcoin. 1 share of a Bitcoin ETF is not bitcoin. Then there is everything in between. That’s a feature not a bug of decentralization.
If you can use it as money it’s great. If you can control the keys - that is best. But hoarding bitcoin and accusing others of doing it wrong is hypocrisy while you spend fiat.
