I wouldn't call the bitmex guys scammers. They were found guilty of not implementing proper anti money laundering regulations but didn't really steal money I think. They also invented perpetual futures which have been a very successful financial instrument. They were only sentenced to six months house arrest for Hayes and probation only for Delo, all served a while ago.
SBF on the other hand did bad stuff and has only served one year out of a 25 year sentence and I'd be a little surprised if he's out in a hurry.
