He had good lawyers around and immediately after the FTX collapse; he very publicly fired them because they wanted him to stop tweeting extensive descriptions of his crimes as a coping mechanism.
Which was going to be a problem for him no matter how good of lawyers he got later.
His defense was always fighting a losing battle here, and likely would have recommended he also try to get a plea deal rather than forcing a trial with this probable outcome.
The Feds had no sufficient incentive to agree to a lesser set of charges, and SBF had no incentive to plea guilty to the exact same set of charges he could instead demand that the government prove beyond a reasonable doubt, which at a minimum would delay the process.

It would have had to have been around 10% if it was in state court in many states, because of the way lots of state bail systems work.
The federal system is very different.
