I don't know, man, what exactly to tell you about this. I just want to buy shares in a company, and I didn’t know which company would be best to choose so that it would bring income in the future. I started googling this question, read many sites and came across one interesting article on this site discovermagazine.com . It turns out it was a whole magazine dedicated to the world economy. And I have always been interested in this topic, and I found so much important information for myself. I think, for myself, someone can also find answers to questions :)
