How will users trust exchanges that suddenly stop withdrawals for any reason, money laundering or otherwise? Most likely there will be panic among users and fear of losing their money forever.
No one knows what the police are doing and what accounts will be frozen. This is one of the biggest drawbacks of centralized exchanges.
This is not good on their side for having an issue like this since they need to do some explanation or even clarification on why such thing still happening. Maybe this is a sign that they do their exit scheme so people have balance on that exchange should be more watchful on what will happen next or if there's an update will release. To many exchange have big controversy these days and I guess this remind us again that we should never trust them.
