I think it is good to see more and more exchanges dying. Too much exchanges mean that there are too much potential scam chances.
If only a few survive they get more cash and can invest more money in security measures. and with every dying exchange the others invest more to get the costumers to their exchange.

And if you store your coins in exchanges it`s your fault. Everyone warned about MintPal and the loss of security at exchanges in general.

But if you want to trade and make profit you have to risk that. Hope people will learn in the future.
