This is Quit sad but there is nothing they could do. when its come to maintenance and security its quit expensive so when you are not getting returns its does not make it a business. I really appreciate how the has made it publicly without running away with peoples asset.
You're right, yeah like Cryptopia
Don't relate with cryptopia because both exchanges closed down for different queries. Cryptopia got hacked and many people's lost their big and small amount of money. I do not know the results of the New Zealand police investigation. But Coinexchange.io is very reliable exchange. And they are going to close down because its more difficult to survive in the bearing market with lower exchange volume. You can withdraw your asset in the specific deadline which is mentioned in announcement. So, don't worry because they already give chances to withdraw your money.
