If you want to make big money, try not to do short-term trading. For altcoins, you can cut the K-line to the weekly line, and then look at the trend. It is clear when to buy the bottom and when to sell the top. The current bull market is far from the top, and the weekly level of the big drop is a good time to buy the bottom. The stronger the trend, the more money you make, and the weekly line is just right.
