I read about their ban from the US financial system earlier on the Exchanges board and it’s pretty surprising to see a centralized exchange of their scale being involved in such activities. Though it’s seems they’re trying to make it look like they aren’t aware by launching an emergency internal investigations.
And you’re right, for anyone still keeping their funds on the exchange it’s better to move to from there immediately.
Their only crime is allowing countries that are not allies with the US transact with their platform especially North Korea and Iran. It might look unfair to ban them from the US market but with the recent hack relating with North Korea, they shouldn't have allowed transactions from that country. I heard they previously blocked transactions from Russia due to sanctions now they'll also lose a large amount of customers in US too. It good that this information was shared here so people trading with the platform would be aware, I believe that after the hacks on exchanges no one from our board would store a valueable asset like Bitcoin with them.
