Fiat is manipulated by governments/banks to control & have power. Whales heavily manipulate crypto. By switching to crypto, isn't it just handing the control & power from governments/banks to a small group of wealthy whales?
Well, it's kind of like, but it also means handing the power to everyone not minding who you are, whether you're rich or poor. That's why it's been said that there is likely to be a bad side to everything that happens. That's why you see today, there are people who make use of Bitcoin for a good purpose and there are also bad people that are taking advantage of the freedom given to them to do evil. Everyone is not the same, we have different purposes.
But the way I see things , cryptocurrencies are not really here to replace the first system. We are still going to have fiat and we are going to have cryptocurrency. It's just going to be as you are seeing it now, you will be able to make use of any one you want to make use of.
