Give me a fulcrum, and I can move the entire cryptocurrency market. This is the principle of leverage. If you don't know how to use leverage, you won't be able to do it. I tried contract trading, and Binance gave me about 12 times leverage. Generally, I use 2 to 3 times for trading. If you encounter a highly certain market or have already generated some profits, you can increase your position and leverage with floating profits.
