One of BitMEX’s security features at one point (if memory serves) was that one (or more) of the principals had to review/approve withdrawals daily. That is likely difficult for them to do from prison or while being detained pending trial or extradition. BitMEX is probably not a great place to have assets that you need access to any time soon right now.
I wonder if the fact that he continually provoked trump... while running an illegal exchange... from within the united states... had anything to do with the charges today? [0]
Unlikely that contributed anything, however, if BitMEX donated to Trump's campaign or stayed at Trump properties, I wouldn't be surprised if this indictment would've never saw the light of day.
