I'm sorry but adding coins is a non sense...
I don't even understand why we do have to pay for MintPal greed...
Mintpal has to run a business, it's totally understandable that they simply can't just bail out every victim of a coin that was under attack in some way. They are in the same learning-process as we are with weekly hyped altcoins and all this different attacks for every damn coin any given time.
To me it looks like they are doing their best. I still hope Mintpal will keep nc2/nc3 after the transition, because I never had problems with their plattform and they can manage volume better than other exchanges. They obviously are on their way to the top and should have such a unique coin like c2/c3 in their portfolio.
I love mintpal too and they are mostly doing great so far. I'm really happy to move there from Cryptsy. But why would I pay for their learning process? When I do mistakes trading unwisely I'm paying with my own money for that. I guess they should pay for their mistake by themselves too.
Just my 2 c2

My understanding is: If they pay for every scam or error by themselves without some help from us customers, they couldn't compete with other exchanges and could be forced to fire staff and would therefore lose their quality edge which got them their good rep in the first place.
It's not "mintpal's greed" that caused the double spend. Get your facts right. It was a flaw in the POW/POS model. If Mintpal has a low confirmation, that is to enable faster withdrawals and deposits. The low confirmations is not the "cause" of the double spend. It merely sped up the process. I don't understand why Mintpal has to "compensate" the traders for the coins they purchased just because it happened at their exchange. If you are staying at a hotel and an assassin comes and kills you, is the hotel management to blame for not having a tank and the army guarding the hotel? Does the hotel owe the victim blood money for his family? Of course not. At most, the hotel loses reputation, which is not to be taken lightly for any running bussiness, but nothing more. Mintpal is no different. Get off this big corporation / small farmer mentality.
Not minty's greed, mintys incompetence.
Because mintpal should understand that the 'flaw' occurs when coins are not staked and securing the blockchain.
How many coins did mintpal have ("in escrow lol") NOT securing the blockchain?
Did mintpal tell anyone they were not securing the blockchain with their coins?
How many coins did mintpal have on account NOT securing the blockchain? (millions? 30% of all c2? 40%?)
I mean come one mintpal, do you even crypto?
