that's was shocking me,i know shapeshift since long time,and this is bad news for those people who still use it,and yes you right,more exchange will open and more will hacked or maybe scamming us,now its hard believe fully to exchange.

reaaly its sad

The first thing about the security systems ==> They are not secure...

Even then most of their customers will not come back to them even if they lose nothing, because the trust is shaken. Why will they now risk even.
there are plenty for other site where they can exchange coins and also without fear 

This is not an exchange, it was just currency exchange site. No perons coins was there at the site.
So it was not that big destruction.

I think shapeshift didnt invest on more security protection for their site and the hackers notice it and they successfull hack and make it down. Just like vixtrade they are knew trading site and they are attack by hackers and now they are not recover their lose thats why they are down now. I lose some btc and altcoin in vixtrade.

This is the flaw in centralized services and will always be vulnerable to attacks. Bitcoin was built to be more robust, with the decentralized nodes and this increase it's security

and decrease it's vulnerability. You use these centralized services at own risk and you should not blame the Bitcoin protocol when these services gets hacked. Well, it still has to

be proven that these services are actually hacked from someone outside of the service, and not people working within these services. 

I noticed quite a few alts were down by double-digit percentages this morning. I'm guessing it's related to this Shapeshift hack. But if Shapeshift is accurate in saying customer funds were not hacked or at risk, this looks like a buying opportunity based on the market over-reacting.

The only people I see losing money in a Shapeshift hack is Shapeshift itself. Customers should feel safe just by how the site operates

People posting not to leave coins on exchange are correct, but that sentiment does not apply to this situation
