It doesn't concern us because if they were managing the exchange well and not misusing the funds of their customers they won't have been found guilty and the attacks on their reputation ends up making their exchange to shutdown. Exchanges are becoming greedy, I have seen that many of them are thinking that they're above the laws therefore they're operating any how without caring about the users making use of their exchanges. Exchanges are failing because they're violating anti-money laundering laws and any individual caught of this violation has to be punished in spite of the market not having a regulatory body. More centralized exchange are always going to fail because they're the exchanges that the government can attack and find faults as they'll always have greedy team members.
