If we talk about transaction fees, bitcoin is indeed cheaper than the transaction fees applied by the banking system. However, you also need to remember that the price of bitcoin often experiences quite significant increases, as has happened in the last few months. So at certain times Bitcoin transaction fees can also become quite expensive due to transaction congestion in it. Apart from that, the transaction fees applied by the banking system from the past until now are quite expensive. But the advantage of the banking system is that I know the costs won't increase too much each year. So even though the transaction fees are quite expensive, the difference is that the transaction fees are quite stable. Therefore at this point I would not say that the banking system is bad, and bitcoin is better. Because both also have their respective advantages and disadvantages. Maybe if we want to send some money across countries, Bitcoin is definitely the most appropriate solution to use. But if, for example, we want to send money within our own country and not across borders, I don't think there's anything wrong with going through a bank too. Because actually, if we think deeper, banking also plays an important role in our lives. Because for example, if we were to sell bitcoin, of course the money would definitely be withdrawn into a bank account. Maybe for countries that have legalized bitcoin, such as El Salvador, you can directly carry out transactions without banking, because in El Salvador there are many shops or shopping centers that accept bitcoin payments. But for people who live in countries that have not legalized bitcoin as a transaction tool, of course to be able to withdraw their money they have to go through a bank first. So the point is that currently bitcoin and banking will always be equally needed by the majority of humanity.
