Bitcoin is a baby in a big world!
Bitcoin is not as big as people think!
Its true based on what you are comparing with in terms of value of bitcoin and even there are some several not too known companies whose value could be more than the total amount of ETH or any popular crypto currency that we are all 'crazy' about. But beyond that, when value are being ascribe to certain items, its not only about the quantitative factors alone but other ground breaking barriers that are being met on a daily basis.
Today, several personalities are talking about bitcoin, Bill Gates will make comments and would be reported in the news, World Bank will make statements about bitcoin and lives will be touched, governments, regulatory bodies, experts, entrepreneurs etc but I have not read about McDonald being referenced to with so much relevance. I know that there are several countries that McDonald does not have outlets but I also know that all over the world with the exception with those without internet, bitcoin has touched more lives and continues to do that more than what McDonald would be able to do now or in the future.
