Even on a logarithmic scale, showing the more pragmatic diminishing returns theory as opposed to God candles of hope, the power law currently shows a trendline price of between $135k and $150k (Depending on which model). The bassline, or support line is interesting at $58k to $61k. Therefore, by any calculation or measure, $66k Bitcoin is an excessive undervaluation. You could go as far as to say that Bitcoin is currently on fire sale. Also interesting to note: the trendline shows an expected value of $161k by December 31st of this year (now just over 5 months away). So, don't let anyone tell you that new ATHs (which would smash the self-fulfilling 4yr cycle theory) are impossible this year. If anything, there is more mathematical justification for an ATH in 2026 than not.
