Some great points there.

WoS yep I only got it to zap sats. I treat it like the ashtray of my unlocked car, basically.

If there's a non-custodial LN wallet for zapping I'd like to know. I can't find one. Preferably if it can work on mobile or desktop, and better still if it can also do on-chain without silly rules and fees.

The rug-pull thing, I don't know how it would work. All I know is too many people still dependent on systems with points of failure. Taking funds is one thing, shutting down wallet servers for popular systems eg Ledger, Exodus etc is another possibility. All surmountable with a modicum of knowledge but most people would be stuck at least until they could phone a friend and considerable damage could be done in a few hours.

There are those who believe Bitcoin was built with backdoors we can't see, maybe even hiding in plain sight, who knows, and that at the end of this year there'll be a massive theft of everybody's holdings. I can't begin to judge that info or the quality of the source, but the reckoning was btc wouldn't disappear but would diminish hugely in value and importance. Me, I'm still betting heavily on it, because this is like WW2 and if only toasters come with guarantees.
