My personal opinion is that anyone who is really concerned about their finances and wants to succeed in investing - should not follow and do what anyone tweets on the Internet. Or at least not before he did his own research on the information in question from this tweet.

People who have a huge number of followers and have a lot of influence over the masses usually do everything for their own benefit and manipulate people, and cryptocurrencies are one of the things that is influenced by a hell of a lot of speculation and manipulation.
