I am not an expert of encryption, so I do not fully understand the following article. However, it seems very interesting that some researchers demonstrated a way of hacking BTC private keys in a security conference in Las Vegas, US.
Any opinion on this? If it is true, the bitcoin price would plummet soon.
No no.Hacking a brain wallet with a weak password and trying to hack a private key are completely different things!! Bitcoin is very secure.It's up to you what kind of wallets you use and how strong the password is. Please don't mix these things up!!
