According To expect they always say blockchain can never be hacked and your information can never be stolen .. But day in day out Hacker are hacking crypto exchanges to steal people asset , ETH Suspended hard Fork because of security reason . HitBTC and Cryptopia are understand maintenance because of hacker . Are they Using block-chain technology to deceive Us ?...
Its different between blockchain and hacker in exchanges, blockchain is safe no one can hack it, And exchanges like HitBTC and Cryptopia, only use blockchain technology but in their platform, they control it, so if exchanges get hack, not because of the blockchain system but mistake by the exchange system
So should we trust blockchain? Yes
