Even if there is mass adoption, do people need to learn about the functionality of Bitcoin if they are trading or saving? We all use a bank but we do not know about how the banking system really works behind the scenes. It is the same for crypto, most people do not know about how blockchains work or how to mine as they are only interested in whether they are making a profit or loss.
that is kind of what is wrong with having a bank because we are trusting a third party without knowing the limits of their control and access and we are just blindly giving away our money for them to keep until we want to take it again but with crypto since we are the ones fully responsible with our coins it will only make sense if we knew the functionality of bitcoin or at least the very basics of it
When we give or deposit our money to the bank to keep until we need it, they don't just keep it, they use it for their business, the loan it out to businesses and individuals in need of loan at a rather high interest rate, they collect this interests, making huge profit on our money and in return give us nothing, most times, they even charge us for sms alert, Atm maintainance charge, account maintainance charge and other various charges that reduces the amount of money we initially deposited, banks are soft criminals, stealing with paper and pen.
This is one of the areas bitcoin has brought or given us liberty on, and I can't wait to see the moment when bitcoin becomes so popular and relevant in our societies that banks begin to lose complete relevance.
