Trump is an intelligent man and he knows some people are into Bitcoin investment and he knows the support of Bitcoin will give him the vote of Bitcoin investors, however trump really do not care about Bitcoin all he cares about is becoming the US president again.
Bitcoin has been used to play politics a lot of times but I'm so happy it will never affect Bitcoin negatively, Bitcoin is now a world class investment very easy for every countries citizen to participate.
Trump is a business man and also a politician why Biden is just a politician and so Trump is using his business tactics to gain more supporters who are in the investing world.
