Hello
I do understand what you are saying but the only reason why People like Elon are successful is because most of the people are weak minded and since the market is indeed Volatile it is very easy for people to trust on anyone who have a big company. People fail to understand that these people are the ones who are only thinking about their welfare. Ofc we have to stop the FUD for sure. But I do think what would work is " right information" , " confidence", " trust in the market".
People are always afraid that Bitcoins will go tulips but that is a whole different scenario. I don't think this is gonna happen for sure in the future. We have seen it grow since 2009.
Do not follow such people, keep holding if you have a good amount.
