Possibly if someone out there really knows everything about it, hackers ans scammer are genius they are smart enough about everything related to internet and computer technologies, so we can't really be sure about it because today everything seem possible all in the name of power, wealth and money
Even if they have the most powerful computer to decrpyt the security of blockchain or bitcoins, it cannot be hacked by anyone else not unless they have connections with Satoshi Nakamoto, but I dont think no one can hack the system of bitcoin.
