What are your thoughts on this?
Considering that Bitcoin is a new digital currency and the software for it is not that mature yet, I don't think what happened recently should be that surprising.
It's beta software that is quite appealing to hackers because there are money involved, so attacks or flaws like these should've been expected. It's the risk the early adopters had to take, and some or most of them made a lot of money in the process by taking that risk.
The only mistake was in believing that Bitcoin was going to be 100% safe forever with no further improvements, and securing the clients and transactions as much as possible. But this is because it's still early for it, and it does have a lot of potential, so I wouldn't give up on it.
Bitcoin also needs a real economy behind it, not just speculation, so the faster that bitcoin economy grows, the better it is for bitcoin.
Are you referring to the attacks that leaked user information? That is a little different than someone stealing 500k from your account right? Furthermore, most major banks will cover fraud charges and by design there are no such protection with Bitcoin.
You don't seem clear about the attack: the hackers copied the wallet file from the person, and then used the information in it to move bitcoins. This is exactly as the system is designed to function - allowing people to back up their wallets, or transfer them to another computer. Essentially, any computer with a wallet on it that is also compromised by viruses, trojans, or other malware is at risk of losing any bitcoins stored in the wallet.
