CDD (Dormant Coin Movement)
Shows how much long-dormant bitcoin moved in a day. The figure is divided by total circulating supply so eras can be compared (supply-adjusted).
How much long-dormant coin moved. Watch out when a bar suddenly gets tall.
How to read this chart
The longer coins were held before moving, the bigger the value. A sudden spike signals long-term holders are on the move, so it deserves attention.
New to this metric?
What is CDD? The amount of coins waking from a long sleep in the closet. A sudden spike means long-term holders have started moving their coins, which is often read as profit-taking near a top.
What is a coin day?
One coin that stays put for one day accumulates one coin day. When a single coin held for ten years moves, about 3,650 coin days are 'destroyed' at once, so the older the coins that move, the more CDD spikes.
Why do spikes matter?
Long-term holders are usually seasoned investors who have watched the market for years. When they move coins all at once, it's often to send them to exchanges to sell, so spikes have historically clustered near tops.
Is a spike always a sell signal?
No. Large moves unrelated to selling, like wallet consolidation or transfers to custody, also spike CDD. So rather than a single spike, look for spikes repeating while price is in a top zone.
