Coin Years Destroyed (CYD) keeps spent coin time as a single accumulating figure, which makes it a statement about how patient owners behave over time rather than about any particular afternoon. Nothing else in this family moves so slowly or so steadily.

Everything else on this dashboard reacts. This one accumulates. The trade is deliberate: it will never call a turn, and when it does move, the regime has genuinely changed rather than wobbled for a fortnight.

What it actually measures

The series holds a long stretch of destruction in a single figure, expressed in years of coin time rather than days. Individual sessions barely register against that total, so what survives into the line is sustained behaviour by aged supply. Read against price, that turns it into a record of how patient holders behaved through a whole market phase rather than on the days that made headlines.

An extended spell down at the low end is the plainest picture of accumulation anything here produces. It certifies that the patient owners sat out the whole period without meaningfully letting go, and no series measured a day at a time can certify anything of the sort.

The line has a memory, and it forgets on a schedule

An event stays inside the reading long after it happened, and then one day it leaves. A large destruction phase lifts the line, holds it up while the market moves on, and then drops it sharply on the day that phase finally ages out.

That fall is not news. Nothing happened on the day the line dropped, other than an old event no longer counting. Check what the market was doing when that stretch began before treating a sharp decline as fresh information, because a good deal of the movement in this series is arithmetic rather than behaviour.

What it does not tell you

It is useless for timing, by design. It moves slowly enough that a turn is only visible well after it began, and anybody looking for an entry or an exit here is asking the wrong series.

It also flattens shape. A single enormous event and a long run of moderate activity can leave the same total, and the line will not distinguish them. Nor does it place an event in time: a high reading says a lot of destruction sits inside the stretch it covers, and it will not say whether that happened recently or long ago. Binary CDD and the raw destruction series carry the detail this one deliberately discards.

How to read it

Elevated. Aged spending has been running high across the whole stretch, not on one day. Historically the distribution side.

Mid-range. The running total sits in its ordinary range, describing background conditions.

Subdued. Aged supply has been quiet across the whole stretch, the cleanest description of an accumulation regime on this dashboard.

Open the Dormancy dashboard and Coin Years Destroyed sits there with Coin Days Destroyed, Supply-Adjusted CDD and Binary CDD.

Common questions

What question does it answer best?

Establishing whether the old coins have been stirring as a sustained phase instead of on one memorable afternoon. Isolated jumps are deliberately shrugged off.

Why does the line turn so slowly?

Because one session cannot shift an accumulating figure by much. That leaves it useless for spotting a turn and genuinely valuable for confirming that one happened.

What does a long stretch of low readings mean?

That the patient owners sat out the whole stretch without meaningfully letting go. It is the plainest accumulation picture on offer here, and no single session could ever establish it.

Why did the line fall sharply when nothing happened?

Most likely an old event ageing out of the stretch the line covers. The reading fell because the past changed, not the present.

What separates it from Coin Days Destroyed?

Same underlying behaviour, different horizon. CDD reads events, this reads phases, and using one where the other belongs is the usual source of confusion.
