In the era of pandemic 2020, Federal Reserve Bank printed paper currency notes which ultimately decreased the value of us dollar USD. And in that period, Bitcoin btc was also stagnant and did not move much. So did bitcoin has losen its value with usd?
Both of your arguments are wrong. There hasn't been any huge US dollar devaluation yet, despite the money printer going brrr. And Bitcoin wasn't stagnant, its price fluctuated a lot in this year, so it's impossible to tell if it reacted to this theoretical US dollar devaluation or not, because there were many ups and downs. And like others pointed out, Bitcoin is up since the beginning of this year, so you are wrong again.
