If I remember correctly listening to one of your interviews, there was actually a bug in hive keychain that caused your power down to reset in the steem/Hive split.. and that cost you some cash as your steem was confiscated.
Do I have that right? and is that bug fixed? that would be the first place you should look.
I am supportive of an Audit, but I would have thought if there is a vulnerability it would have been exploited by now, given the market cap of Hive is in the 100m+. Its more for the reassurance that future updates and that's why I am supportive.
