I'm having trouble understanding how a typical investment works, and so far most textbooks are pretty vague with their language.
Let's say you invest 200 dollars in a startup (let's start small). The startup ends up collecting 50k dollars and by the end of the year the company made profits in the value of 150k dollars.
How much, as the investor, am I supposed to get out of this? Is it percentual, or are other calculation methods applied in investment?
Also, is this a one-time win as it was a one-time investment? Or once I invest in a company I get to hold shares for a certain amount of time and so can calculate with (hopefully) some gain as long as the company remains sucessfully for the next years?
