What the cohorts are
A coin is typically classified long-term-held once it has stayed unmoved past a threshold (commonly around 155 days), and short-term-held below it. The idea is behavioral: coins held through that window statistically tend to keep being held, marking conviction rather than speculation.
Why the split matters
Short-term holders are the marginal, reactive supply — more likely to sell into volatility. Long-term holders are the patient base whose accumulation or distribution tends to align with cycle phases. Watching supply shift between the cohorts is a lens on who is buying weakness and who is selling strength.
How it connects to valuation metrics
Cohort logic underpins several on-chain gauges. Realized-value and cost-basis metrics like MVRV, NUPL and SOPR can be split by cohort to show, for example, whether long-term holders are spending in profit — a common late-cycle signal. Read cohorts as slow context, not a timing trigger.
