I stopped advising people to self custody, it's a lot of responsibility, if something happens to their funds its on you, what i do is just explain the options and tradeoffs. Self custody is hard, don't try to fool people, for most people having the coins on an exchange is still the best option.
Bitcoiners need to dump Core. Decentralize node implementations. Get the economic majority, fuck suitcoiners and exchanges, build circular economies, and decentralize hashrate. All this before it's too late.
