Glassnode's long-term holder (LTH) cohort — defined as supply held over 155 days — decreased by approximately 28,000 BTC in May. The conventional read is that long-term holders are distributing into strength. The underlying composition tells a more textured story.

The cohort definition refresher

LTH supply is calculated dynamically. Each day, supply that crossed the 155-day held threshold gets added to LTH. Coins that are moved (regardless of how long they were previously held) drop out of LTH and become short-term holder (STH) supply. The net change is the "LTH supply delta."

When LTH supply decreases, it can mean two distinct things:

  1. Distribution: old coins are being moved/sold (real distribution event).
  2. Cohort aging shift: the rate of coins newly crossing the 155-day threshold is slower than the rate of older coins being moved.

Both produce the same headline number. Composition matters.

Decomposing May's -28K

Breaking down the 28K BTC LTH supply reduction by coin age at the time of movement:

  • Coins held 6-12 months at movement: -14,200 BTC. This cohort is "freshest LTH" — barely past the threshold. Moving these out is often profit-taking by recent cycle entrants.
  • Coins held 1-3 years: -8,400 BTC. Mid-cycle holders. Distribution here typically signals belief that we're closer to the cycle peak than the trough.
  • Coins held 3-5 years: -3,100 BTC. Notable; this is conviction-cohort.
  • Coins held >5 years: -2,300 BTC. The deepest cohort. These coins moving is rare and often headline-driving.

The composition shows two distinct stories overlaid:

Story 1 (the larger): recent-cycle entrants taking profits in the 6-12 month bracket. This is normal and consistent with a mature mid-to-late cycle phase. Not alarming on its own.

Story 2 (the smaller but more notable): material movement in the 3-5 year and 5+ year cohorts. 5,400 BTC of deep-cohort movement is above the trailing 12-month average of 2,800 BTC/month. This is the cohort whose behavior is most predictive of cycle peaks historically.

What deep-cohort movement has historically meant

Looking at the previous two cycle peaks:

November 2021 peak. Months leading up showed deep-cohort movements averaging 4,500-6,000 BTC/month for 8 consecutive weeks. We are currently at ~5,400 in the most recent reading, after readings of 3,200 and 4,100 in the previous two months. Trajectory is consistent but not yet at the 2021 peak-warning levels.

April 2024 local peak. Deep-cohort movements peaked at ~7,200 BTC/month before the price drawdown. Two months of >5,000 readings preceded that peak.

The current trajectory looks more like the 2024 local peak pattern than the 2021 cycle top pattern. Doesn't mean nothing structural is happening — it does mean we're not yet at the canonical "deep distribution" signal.

Counter-flow: where's the buying

LTH supply going down requires STH supply (the recipient of the moved coins) to go up unless coins are leaving the network entirely. STH supply increased by ~31K BTC in May, indicating coins are flowing into newer holder hands.

Two questions emerge:

Who are the new holders? ETF AP firms accumulating to settle creation orders are one source — but those coins typically don't appear in standard on-chain wallets, they sit in custodian-managed cold storage that may or may not show standard age signatures. The on-chain age metrics may understate ETF-related accumulation.

Are STH coins being held or flipped? Average STH holding period in May was 19 days, slightly below the trailing average of 22. Slight elevation in flip rate but not dramatic.

What this means tactically

Two scenarios consistent with the data:

Scenario A: Mid-cycle distribution. LTH distribution continues at current pace (~30K/month) for 2-3 more months before reaccelerating. Spot stays range-bound. Eventual reacceleration of LTH supply growth confirms cycle continuation.

Scenario B: Late-cycle warning. Deep-cohort movement continues to rise (above 6K/month over next 2 months). Combined with other late-cycle indicators (futures funding persistently positive, MVRV ratio in distribution band) this becomes the canonical cycle-peak setup.

The data doesn't currently distinguish between these. Watch deep-cohort movement specifically as the leading indicator.

Trade implications

For directional positioning:

  • LTH supply changes are slow-moving and predictive over weeks-to-months, not days.
  • Don't trade short-term off this. Use it for position sizing decisions on multi-month horizons.

For risk management:

  • If deep-cohort (3-5Y and 5Y+) movement crosses 7K/month, reduce exposure or hedge.
  • Current 5.4K reading is informative but doesn't meet that threshold.

Bottom line

LTH supply distribution in May is real but composition is mixed. Recent-cycle profit-taking dominates the headline, but deep-cohort movement is elevated relative to trailing average. Not yet at cycle-peak warning levels.

Watch the 3-5Y and 5Y+ buckets specifically. Those are the cleanest read on conviction-holder behavior.
