In this video, I discuss why self-custody (holding your own Bitcoin private keys and running a Bitcoin node) is important both for Bitcoiners themselves, as well as for the Bitcoin ecosystem as a whole.
Self-custody teaches people how to be adults when it comes to their money. By contrast, fiat money is all about asking for permission to send a transaction, or help reversing a transaction.
Self-custody leads to more decentralization of Bitcoin holdings, while putting power back into the hands of the people when it comes to protocol changes or forks.
Bitcoin was created to be used as a bearer asset, so users should seek to take full advantage of this. Bitcoin is one of the very few assets in the world that doesn't have counter-party risk, if you hold your own private keys.
