There are two types of people who make money in the cryptocurrency circle by their strength!!!
One is to use contract leverage, open contracts to bet on the direction, continue to hold if it is right, look for opportunities to increase positions, and stop losses if the direction is wrong. For example, Xhuang, Xzhai, and Xni use this method, and the success rate is less than one in ten thousand.
One is to do large-cycle and trend trading, which is also a test of human nature. Even the spot fluctuations of altcoins are large. Without a good enough mentality and pattern, you can't play. About 20% of people succeed in this method.
As for the remaining 80% of people, they basically play with contracts randomly, or trade frequently in short-term, or do some other tricks, so they become the source of profit for the first two types of people. (Those who rely on luck will not be discussed, they are not representative)
