There are two types of people who make money in the currency circle by strength:
One is to use contract leverage, open high-multiple bets on the direction, continue to take it 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 it. About 20% of people succeed in this method
As for the remaining 80%, they basically play with contracts randomly, or frequently trade in short-term, or do some other tricks, so they become the source of profit for the first two types of people.
