I was going to say I seriously doubt they are keeping the bulk of the coins in a hot wallet. There have also been issues/exploits with malleability concerning POS coins... remember the whole blackcoin CryptoRush debacle?
Do you have a link to this? I'd like to read about it.
This is the main thread that was started about it back in March, just keep in mind you have to filter through all the lies and bullshit that CR tried to push on people.
https://bitcointalk.org/index.php?topic=529779.0There was a discussion of how the issue with malleability related to POS coins was updated by the major exchanges like Cryptsy early on so they didn't have any huge problems.
Ok thanks for the information.
So a the main issue was they were using the "accounting" system perhaps incorrectly, and not using any other method to double check inputs/outputs. In addition to that they were allowing the hot wallet to stake, thereby casing even more confusion about it's users balances.
