@cbcnews: Hackers reportedly drained more than $100 million US worth of bitcoin from Coldcard hard wallets, according to blockchain intelligence firm Galaxy Research. Created by Toronto-based company Coinkite, the wallet is marketed as 'cold storage' for bitcoin users who want to keep their keys offline and has been widely praised by users and security experts as one of the most secure places to store bitcoin. It's still unclear who is behind the attacks. #Bitcoin #Coldcard #Hacking #CBCNews
