I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it. I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.
But, is it possible?
Hacking bitcoin will be a very difficult task and will requires much effort to get pass through blockchain. This method seems to be not efficient and also not practical because it will be expensive to do. So I think hackers will lose interest to hack bitcoin since the security is heavily tight. Also, I suggest to all to beware of the links that you click and the emails you received to prevent hackers from fishing to your computers.
