>SBF stole billions; enough money to make it worth going through every minute of the last decade of his life with a fine-toothed comb, he worked with a ton of other people who have knowledge on his methods (and are young enough to desperately want to avoid spending decades in prison themselves- so they will testify), and he was basically plugged into one device or another at all times.

This is a good point... The fact that he has billions probably makes it worth it to put a bunch of federal agents to work and crack his case. However, I still think he probably managed to sock away a few millions of dollars (a small drop in the ocean compared to his fortune) in offshore accounts/crypto wallets (Russia/China?) that may not be worth pursuing.
