When analyzing crypto market trends, it's important to consider various time frames in order to get a comprehensive picture. For example, while a short-term trend may be reversed by a single day of high volume trading, a longer-term trend is more likely to be driven by sustained changes in volume. This was certainly the case in early 2021, when the reversal of a long-term trend was signalled by a peak in volume followed by a sustained period of lower volume. While this type of analysis is not foolproof, it can provide valuable insights into the underlying dynamics of the market.
