I'm not your attorney, but it could be prudent, to hire an attorney in Florida and seek injunctive relief to essentially 'lock' cryptsy down pending an investigation. Your issue more likely than not is dealing with the fact that you signed an arbitration clause. However, now you've got fraud involved and attorneys cost money :/

in the alternative, if you know anyone who is in the class action and a member of the class, it could be beneficial to see if any similar relief has been requested. the fact that their are also personal and possibly business bankruptcy proceedings all going on at the same time makes it a nice mess... which is great, if he's in china lol
