People still go around believing in bank compares to BTC
Without the knowledge that BTC can help them become as free as they want, just as this man carries cash around.
Cash is deflationary, and BTC is increasing in price.
Do you know that in 2023 and 2024 Nigeria appear as the top 2 country in adoption of cryptocurrency globally?

There's different between keeping some money in the bank for the sake of spending it within just a short period of time and then saving a huge amount in the bank for a long period.
For the majority of people that are aware of Bitcoin, if they have intentions of saving some money for a long period of time, I believe they uses the money to buy some Bitcoin and hold for a long term.
For the other people that you see keeping money in the bank, I believe the cycling period of that money is too short, so they just prefer to keep the money in the bank since they will be using it within a short period of time.
For majority of people, Bitcoin is for investment purpose for them, while bank is just for quick access to cash or money to spend.
