My mainstream investor friends do not own any crypto, and they repeatedly gloated to me with something like, "wait until the US government releases FedCoin!"

Well, we already have FedCoin.  It's lost 99.5% of its purchasing power since 1913.

Also, I tell them that their envy and regret at missing out on the rally is not an attractive character trait, and it only weakens their ability to identify attractive investments.
