This message by the Kenyan president https://twitter.com/WallStreetSilv/status/1640018026589290498?s=20 is a request to Kenyans to stop buying and hoarding US dollars. The country has no forex and over the past couple of months the exchange rate has moved from 120 to 141 as people stock up on dollars. It is not a prediction of his lack of faith in the US dollars are the twittercryptoverse is making it out to be.
