Despite the well-known fact that a beginner should have knowledge about cryptocurrency before starting to invest, many beginners have earned a profit without having either knowledge or experience. But this is only possible in a bull market, when the price of the coin increases every day.
Actually a beginner that that doesn't have the knowledge can earn profit but they are at higher risk of losing everything than the beginner that have the knowledge because he has all what it takes in any circumstances. Getting knowledge of anything you want to do before doing it is very good and is the best. For me I advise everyone to get the knowledge of what they want to do first before starting it.
