One possible reason why bitcoin was made is because of the non-transparent and over printing of US dollars. This could be one of the reason why some people are starting to join into the cryptocurrency world and use bitcoin. But it is still too early for bitcoin to replace bitcoin since the world is not ready yet. One day when there will be another global economic recession due to the overprinting of US dollars a big number of the populace will be migrating into bitcoin.
Yes you're right. It's just like US helping bitcoin to patronize by people because of their wrong moves. But as you said it yet the time for bitcoin to replace fiat because a lot of people still don't have any idea about cryptos. And I'm also hoping that that bitcoin price will go up soon.
