Matrixport: Is the increased frequency of significant declines within 30 days an indicator for identifying a bear market?

Foresight News reported that Matrixport stated in an article that a common way to determine whether bitcoin has entered a bear market is to observe whether significant declines within 30 days occur more frequently. During a bull market, a drop of more than 20% within 30 days is relatively rare; while in a bear market, such declines tend to happen repeatedly. Meanwhile, market momentum had already weakened by mid-2025: from the 30-day rate of change (ROC), the upward peaks have been consistently lower, and the buying momentum has also been declining in tandem.

Experienced crypto investors understand that bear markets are a natural and recurring part of the cycle, and often create conditions for the next round of recovery and upward movement. However, bear markets usually do not decline in a straight line; even within a larger downward trend, there are often significant interim rebounds. Therefore, investors should remain disciplined and continuously look for more cost-effective interim opportunities as market conditions change.
