Being one of the famous personality around the world, Elon Musk is using his tweets to pump up the doge coin. I can't say that he can dump bitcoin alone with his tweets because there are other big players involve in it too but for dogecoin, he is single handly pumping with his tweets. But this cannot continue forever. Sooner or later, his tweet will have no effect on the prices. I wonder when that time will come ?
true, not all tweets made will affect something, without the support attached to him. So far, all investors, the company has always been fixated on what is said, even though behind it all we have to understand that as a businessman, he will have a specific purpose, what is certain is to get the benefits that can be obtained.
I hope that in the future, things like this do not need to be questioned and don't be exaggerated, because it is only for harm. everything can not be controlled properly in a way that is only for the benefit of its own interests.
I believe the same as you that gradually everyone will understand what he tweeted, and will not affect the development of the progress of crypto itself.
