Despite the known facts is absolutely shocking that an economist promotes a cryptocurrency (even worse: a "meme" one that was created minutes before his tweet), as is widely known that there's no value at all in there but pure speculation, that's what puzzles me the most. If people with little knowledge on economics know this how can't he? How can a president with an army of advisers let him publish something like that? Even if it was his very own mistake it is really unbelievable that people around him didn't know a thing on the matter, is just simply not possible. He really should stay away from the stupidity of social networks and do better for the country that is still going through hard times. In one occasion he also denied the climate change, possibly due to Trump's position, showing that he doesn't know a thing about certain topics. In such situations he should really shut up and get properly informed.
