Hmm in the world of Bitcoin, a closed source wallet = 99.99% chance of malware designed to steal your bitcoins.
Thus far, the users of our wallets have not reported any suspicious activity at all.
I can confirm this.
I've been running 3 wallets on 3 different PCs since launch and I still have my BTCs,
which seem to be worth less by the minute at the moment.
Think I'll keep mining AIR.
