2. A fast fall and a slow rise indicate that distribution is occurring.
Rapid fall but slow rise indicates that the market makers are gradually selling off, and the market is about to enter a falling cycle.
3. Don't sell when there's volume at the top, run quickly when there's no volume at the top.
The trading volume at the top is large, which may continue to rise; however, if the trading volume at the top shrinks, it indicates insufficient upward momentum, and one should exit as soon as possible.
4. Do not buy when there is volume at the bottom; you can buy when there is sustained volume.
A volume increase at the bottom may indicate a continuation of the fall, which needs to be observed; continuous volume shows that funds are continuously entering, which may warrant a buying consideration.
5. Trading coins is about trading emotions, and consensus is about trading volume.
Market sentiment determines the price fluctuations of cryptocurrencies, and trading volume reflects market consensus and investor behavior!
