Why do people have to consider words from a celebrity to be correct?
It's because people thinks they have the 'authority', that's why majority follow their tweets and then react positively and negatlively.
This is a case a concern for sure. People are not able to think for themselves in some case. Which can create a very dangerous situation for themselves and even an entire community with this mindset.
Unfortunately, this is true, and that's why we have leaders and then we have followers. But we do have a choice though, we really need to make that important decision, not just in crypto, but it applies in every aspect of our life.
Why would anyone invest lots of money into a project that is quite obvious has no involvement by any people? Referring to Dogecoin and people who invested into it. This is like going to an empty store that is closed and dropping your money into the mailbox just for the fun of it.
In this case it is Elon Musk saying it would a great idea to dump money at an empty store.
Greed for one, they thought that they can make a lot money in Dogecoin. The whole market is full of this individuals, others became super rich, but majority losses because they chooses to follow and didn't used their common sense.
