With that been said, if we do some research about the inflation level of fiat currency during the total lockdown season we can say cash is trash while bitcoin is king cause it maintain a stable price
I would be particularly cautious in drawing such conclusions
Bitcoin is king simply due to the fact that fiat fails. As I see it, one thing is to be a king on one's own terms and merits (which Bitcoin is not), and the other to be a king through the failure of something else (read, by luck). In simple terms, if governments didn't destroy fiat by insane money-printing conveniently couched as fiscal stimulus, quantitative easing, and the whole spectrum of other euphemisms, fiat would still reign supreme
You're absolutely right cause Bitcoin was seen has king due to fiat failure but we cant the government are not aware that their act of insane printing of fiat and not setting a strategy which will make fiat supply limited was the one reason affecting fiat values. The question is why making the same mistakes over again?
