Not entirely accurate, because Fidelity and a couple other ETFs don’t use Coinbase custody, perhaps Grayscale and Bitwise. The rest, yeah. It makes sense to buy a few to spread custody risk. Wall Street has the the feds by the balls so I doubt there’s as much of a risk for now compared to self custody risk. You do you, though.
As for Trump, lol. He’s only about applause lines. If he can get more applause five minutes later by saying the opposite, he does.
