In my opinion, I do not think fiat money will be replaced by cryptocurrencies as most of the people has not yet become familiar and mass adaptation is not yet in full scale in the current situation. Moreover, the popularity of the cryptocurrency is now being recognized by many people and the advantages it has served to the public has a remarkable effect with respect to transaction payments which is much faster and convenient to the user.
We have already seen that even UNICEF is accepting Bitcoin Fund. As we can see people prefer shopping online rather than going Shopping mall as a result Amazon owner is richest person in the world. we here will not discuss the shopping , but rather look at technology and its use. Technology new idea are being accept by people . Furthermore crypto are instant and more secure compare to fiat currency. Definitely, ccryptocurrencies will take time to be familer and gain trust from people.
