Bitcoin is still unhacked, what was hacked is MtGox and their silliness in using unsalted password and md5 which had been discouraged for years from use for hashing sensitive data.
http://gizmodo.com/5824503/anonymous-bitcoin-purchases-arent-actually-anonymous You are not anonymous on the Bitcoin network and that makes it very unattractive to me. Im so glad I did not spend hundreds of dollars on Bitcoin when it obviously is not secure or anonymous like it claims. I really wanted to be apart of this. I think its a great idea and it the future of currency. Can someone please convince me to look past these major flaws.
Bitcoin does not claim to be anonymous like cash, just closer to anonymity. If you don't put your identifiable information all over the place and take special care, then even that research analysis method would find it close to impossible to pin you down.
