I agree that Elon Musk contributed just a little in terms of hard work and time spent to make Bitcoin the way it is now. However, many people considered him as a type of hero all because of his influence. People are listening to him and even if they are doing it blindly nothing can deny the power of Elon Musk especially at the time when Bitcoin is already on the bull run stage putting more gas to the fire, as they said.  On the many technical sides, nothing beats the people as mentioned and enumerated above and we should be thankful for their many enormous contributions which actually led to the creation of the whole cryptocurrency industry not just Bitcoin.
