Satoshi build Bitcoin and as a coder, he really listened to community feedback and tried to explained it because Bitcoin was (and is) still very technical. Bitcoin is a great technological piece because Bitcoin needs to be safe from hacker. Much money is stored in Bitcoin network and if it's not safe, we are screwed, everyone.
Bitcoin was not hacked, not because it is safe or because Satoshi developed it securely, and if this is true, it is because of its nature. Bitcoin, by its central nature, cannot be hacked because it is not the servers of a central company or service, but only paired spending is possible if the hackers have the longest chain starting from 51% from the network to launch a successful attack. learn a lot in a short time by reading some books or watching YouTube videos.
