If the world of Economics was so easy to understand, we wouldn't have highly reputable economists disagreeing about what's going on and how to solve issues. Investing wouldn't even be a prospective career if it was something so simple and obvious that anyone could do it. There are a lot of events that influence the economy, and many of those are not specifically economic but come from other areas (public health, politics, ecology, etc.). It is good that we live in a world of information and that a lot of information is out there. But that doesn't mean it's simple to navigate it. I'll finish with a simple example: laws are public, anyone can read them and make decisions, and yet in serious situations people to refer to lawyers and lawyers are always in high demand.
It's not hard to understand world economics, it's very easy. In the world, there are rich, average and poor countries. Rich countries are rich because they invented the economics and made other countries dependent on that, they created the game with rules that suit them well but not so well for poor countries. If I make a chair in the United States, I'll be paid extremely well for my job but if I create a chair in some other 3rd world country, it won't even be enough for me to buy the food. Look at this, I get paid very differently for doing exactly the same job.
USD and Japanese Yen, both are papers that cost exactly the same to create but carry different values and that's done on purpose. In reality, money is absolutely nothing and it's purchasing value is faked.
How can Bitcoin be 60K one day and 40K in a few hours when nothing has happened except some manipulative news? Why should it's value go down if Bitcoin stayed Bitcoin and there are no technical problems? The whole economy is manipulated by those who have the power. They can make you work for 5$ per hour and can also make you work for 50$ per hour, as they wish.
