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.
Our job is only to use the exchange for transaction purposes and buying and selling. Problems of abuse and their customers will be faced with the laws that apply in the area where the exchange operates. Therefore, we have to be smart about using exchanges and not using them to store the bitcoins we have. The mistake people make is not understanding how unsafe it is to store bitcoin on an exchange so that when they have problems they will lose the assets they own. There have been many exchanges that have experienced problems in recent years and they generally find it difficult to escape legal charges that result in blocking exchanges that do not obtain operational permits anymore.
But what we need to remember is that exchanges are not a place to store bitcoin because the level of security is still considered sufficient not safe. If you fail to understand a safe place to store bitcoins then any losses that occur will be the full responsibility of each of us. Now that there are much safer wallets for storing bitcoins, anyone has to find out which wallets can provide a sense of security for us to store bitcoins.
