CYCLESCOPE · HOLDER BEHAVIOR
Coin Days Destroyed
An age-weighted measure of Bitcoin moved on-chain. The older and larger a spent coin is, the more coin days it destroys.
Volume weighted by coin age
One BTC held for 100 days destroys 100 coin days when spent. This gives older coins more weight than the same amount that moved recently.
Coin age times amount
Σ (BTC spent × days since previous movement)LOOK CRYPTO shows the current reading and its 30-day change to separate direction from the series scale.
A spike means old capital is moving
- RisingOlder and/or larger coin amounts are moving; possible distribution needs confirmation.
- FallingOlder supply is quieter, which is consistent with holding.
- SpikeCheck transaction destination, LTH-SOPR and exchange inflows.
Do not equate movement with selling
CDD is most useful with LTH Supply: falling supply alongside rising CDD strengthens the old-coin reactivation signal.
Large transfers create noise
Custody migrations, UTXO consolidation or internal transfers can produce spikes without market selling. CDD has no universal cycle-top threshold.
