The main reason why people leverage is because they do not have large amount of money to trade, that is why they instead think of going 2x, 3x or more. It all depends on experience, the leverage used and patience. Some people are good enough to turn smal amount of money into something good. If anyone can not start to trade like this will lillte leverage like 2x, then the person can not be a good trader or will lose a lot before becoming a good trader.
