According to the cyber media Tokenist, based on the results of their survey not long ago. The survey involved 4,852 respondents from 17 countries. According to the survey the number of people who trust Bitcoin more than large banks, increased by 29 percent in the last three years. The survey also showed differences in the generation's views about Bitcoin and traditional banks. 51 percent of millennials trust Bitcoin more than traditional banks.
So the conclusion came based on only 4,852 respondents? I guess the user base which responded weren't quite diverse.
I would say more people know about banks and how they work when compared to bitcoin. It is going to be a total lie when you say bitcoin is more popular than traditional banking. If bitcoin was indeed more popular, everyone would know about and everyone would use it. They would prefer bitcoin over fiat. After all, there is no one stopping them from using it.
