In my opinion, after taking office, Trump and Biden had some coincidence when the value of bitcoin increased. But to me, Trump is more friendlier and correlated with bitcoin's value. As for Biden, maybe not. The main reason that bitcoin and cryptocurrencies serve as a lifesaver for an economy in disarray after a global catastrophe called covid 19. Depression and depletion of securities has led to an explosion in the crypto market they we see now.
