Non-crypto billionaires have bodyguards for a reason.
I'm pretty sure it's easier to defeat the 2FA at my (major) bank than to try to hide a few hundred millions in crypto through tumblers.
That may be, but if someone defeats the 2FA on my bank account they still need to transfer the money out to somewhere, and that will leave a trail far more obvious than any tumbler. It's also not a quick process. If they're adding a new account and immediately transferring large amounts out to it my bank is going to have questions.
