Till now bitcoin is not much popular than USD because USD is almost known in very country and every people know about usd,but in case of bitcoin only people who are at online only know about that but government accepting bitcoin may increase popularity of bitcoin
I'm not sure that bitcoin will someday be as popular as the dollar. They do not need to be compared. Bitcoin is an alternative coin. Not everyone will use bitcoin. It's all about trusting
Yeah, and I don't think we can have the same trust like how people trust fiat or USD for our bitcoin, right now the number of users is relatively low compared to the users of USD which I believe the most popular legal currency in this world. Bitcoin is a success already and there is no need to think of beating USD as in the end we will need fiat to convert our bitcoins.
