[Analysis: Current BTC short-, mid-, and long-term holders' costs are converging, often indicating a phase bottom in a bull market] BlockBeats News, October 30, analyst Murphy published an article stating that based on the cost basis of different holder groups (short-term, mid-term, and long-term holders), the cost lines of each group repeatedly cycle over time from 'expansion to contraction, then expansion, then contraction.' The expansion phase represents a strong trend, while the contraction phase indicates a weak trend. Between the expansion and contraction phases, there is a transitional period of 'cost reversal among groups,' signaling the end of the weak trend. Currently, the cost basis lines of each group are showing a standard contraction pattern, and the costs among the groups are converging. If BTC remains in a bull market cycle, even though BTC is still in a weak trend (sideways consolidation), its price is highly likely approaching the bottom range of a phase correction.
