I mean we can't really trust both the banks and the whales, banks are just no use since the money you save doesn't really earn a good amount of interest on it as with inflation it just wasn't recommended, whales as well hold a huge volume of cryptocurrency so it just makes the investment risky because when they sell it is going to make a huge effect on the market making it drop a huge percentage.
There is no reason for us to trust banks or whales because their purpose is the same as ours is to earn money to take care of life. No one is good enough to help others without getting benefits for themselves, if in their position, we would do the same as them, all need money.
But I disagree with you saying that banks are useless. Do you use banking in your life? Banks are more than just depositing money and receiving interest, as you said they are an institution and provide a lot of services to users. If you need to borrow money then only banks and centralized institutions can lend you money, bitcoin cannot do it for you.
Yeah your right, I guess even though I don't personally like banks it's still a great platform I guess since it is very convenient compared to other platforms and there is nothing really we can do about it because it is a part of how the currency circulates in our country, the easiest way to save money is just to deposit it on our banks I mean it wasn't really a great interest compared to other savings that there was no risk. Here in my country, I could probably find up to 11% interest including the bonuses where you need to actively use the platform in order to get that kind of interest but if you're just going to save your money there, the interest would probably be 2.5% to 3.5%. It wasn't that bad but while you're still saving money it's a good addition I guess. Of course, there are a lot of platforms where you could easily use banks compared to cryptocurrency, and banks/fiat money are just already accepted and trusted by the people, but it is just not recommended to put a big amount of money because we should use our money to work for multiple sources of income.
