Who the fuck cares of the FEDS outside of America - really come on.... US is not the world & they even have no US clients, lol.
So now you are cut off financial world literally as your banking system is broken but in meantime on whole planet nobody cares of your own rules. I am pretty sure (and know) all exchanges have communications with all kinds of officials incl. law enforcement worldwide as all must give out infos when court rules are presented.
If all went bad then max. USD is de-listed from exchanges what would more start a new exciting moment in history as it would litterally loose complete force of being the "major currency" worldwide - as crypto will win, thats sure.
Yeah and it is of course legit but in that situation they can not do a lot as it is not a company what has any relationship except listing USD - like I said all larger exchanges worldwide are anyway long time in communications with various officials. Finex earned a few m USD / day the last year nearly what can be easy calculated so in fact that company was never such well positioned & capitalized as now.
I would be more concered of Coinbase and Bitpay (so all US based nobody I know would ever use as non-US based human) as nobody know till today what is even with that dead hot-wallets from them + multiple other stuff - lol.
But you are right.... time will tell anyway :)
IMHO storing coins on an exchange is always a bad idea - except the % you can lose, thats nothing new. And buying steem on top is in my eyes the worst - I drive with my HODL strategy perfect since 2012. ^^
