This is why I don't subscribe to OPs groupthink.
I'd rather have my friends and family with me when the whole thing comes crashing down. If that requires them starting with a custodied solution, so be it.
I onboard people with Strike. You can't buy shitcoins. Then once they get a meaningful amount saved, they'll likely have gone down the rabbit hole some and will then be serious about self custody.
This shit has levels.
