Around my environment, its just a few youths knows about cryptocurrency and the few that knows only hears about bitcoin. I think the main reason behind many people not knowing is because most nations have fought cryptocurrency against taking out the fiat banks, so they refused making it legal tender for more publications.
some countries do prohibit the use of Bitcoin as a means of payment. but most legalize the ownership of Bitcoin assets as Investment. more countries have finally opened their minds to the assets that have grown so fast in recent years.
I think young people will be more interested in Bitcoin than in putting their money in the bank. young people nowadays buy more stocks and they are quite open to trading digital assets. it's just that, not much education is provided for young people who are interested in Bitcoin and cryptocurrencies.
