How Do YouTube Payments Work?
Youtube payments work in various ways. You can earn money from ads, the ads will usually pay you from the amount of times the ad can appear on your screen. From the youtube itself, you earn money from views. If you earn 1 million views daily (such as pewdiepie) your daily earning should be somewhere from around $250 to $4000. If you want to know more, there is actually a website that calculates the youtube money.
