Trading experience: The most taboo thing in trading is frequent exchange of positions. There is no need to exchange the coins with the bottom chips. There are endless hot spots in the market. If you want to seize every hot spot and exchange positions, the final result is often nothing. Can't catch it. Hold a few bullish coins to follow the trend. This is the most stable way to make money without getting tired. In the currency circle, if you feel that making money is tiring, it probably means that you are going in the wrong direction​​​
