Robert Kiyosaki is a famous author, being "Rich Dad Poor Dad" his most recognized book.
While he was in his podcast he said the people must sell their USD and buy Bitcoins, becouse he don't trust in cental authority points, like Federal Reserve. Other great point for Bitcoin is that can not be controlled by "elites", politicians and others...
In his opinion the governments are using the COVID to hide the bankruptcy of the majority world financial system.
The national banks don't like gold or bitcoin becouse they can't create It...and the European Central Bank and The Federal Reserve are "printing" a lo of money, or best way to say It: increasing the monetary mass, so, Kiyosaki think that USD and Euro will create inflation...USD specially.
I have to say that I'm not agree with Kiyosaki, I don't think the governments are using the Pandemia to hide a international bankruptcy, I think that massive bankruptcy are normal in a central banks system and the "fiat money" is inmoral due to is impost by force. And Bitcoin or Gold are free. The good money don't need to force anyone to use It...
In addition non-fiat money are more useful and prevent economies for government "experiments" like socialism or hard interventionisms.
If you increase the monetary mass maybe you will create inflation and this is a hide tax for people, OK, but the true disaster using Fiat money is the fact the economy is disorted by arficial interest rates of central banks and the recurrent crisis asociated to capitalism, but central bank is an anti-capitalism element.
When central banks disort the interest rates get the business see opportunity where there is not and when the central banks end the "expansive" period, the interest rates comeback to the real ones and all "fake" business crash.
Can Bitcoin replace fiat money? I don't know, but I know that fiat fail, we have a choice, that is good.
