OLD COINS, CDD AND VDD
Are old Bitcoins waking up?
Some Bitcoin sits still for years. Follow when it starts moving again, and what busy stretches have lined up with before.
How busy old coins have been since 2013
How busy old-coin movement has been, averaged over about a month and ranked against the four years before each day. Near 100 is the busiest of those years, near 0 the quietest. Hover or tap for a day’s reading.
Price uses its own log scale on the right. Compare timing, not vertical distance.

Right now
Old coins are stirring, moving more than usual.
That is busier than on a typical day of the last four years. Over the past 30 days, old-coin movement has held about steady.
Last four years
Today’s reading is 54.7 out of 100, the 55th percentile of the last four years, in the busier half of its range.
0 is the quietest day of those four years and 100 the busiest, each day’s movement averaged over about a month.
The old supply
33.6% of all Bitcoin has not moved in five years or more, by the age record for 28 Sep 2026. The biggest of the three oldest bands is 10 years and up, with 17.8%.
Some of these coins may be lost. Others belong to people who have chosen to keep holding. Age alone cannot tell the two apart.
In dollars
Weighted by Bitcoin’s price on the day each coin moved, and averaged over about a week, old-coin movement is busier than usual, at the 78th percentile of the last four years.
Both views agree: by coin count and by dollar value, old coins are busy.
What changed
Old-coin movement has been above its usual level for the past day. The reading fell from 64.8 to 54.7 over the past month, since 28 Aug 2026. Over six months, since 28 Mar 2026, it rose from 16.7.
What it has meant
Counting the days above 90, old coins were busiest in 2013, 2017 and 2024, each a year Bitcoin’s price set new records. Counting the days at 10 or below, they were quietest in 2022 and 2023, when the price set no new records.
Busy spells have also come in steep falls, as in late 2018 and late 2022, when long-held coins moved as the price dropped. A move shows coins changing wallets, not always a sale, so read the line beside the price.

Old Coin Activity
Where it stands today
Old-coin activity is 54.7 out of 100, above its usual level for the last four years as of .
What does this page measure?
How busy Bitcoin’s long-held coins are. Every coin that moves carries its age: the days since it last moved. Add up those days for every coin moved in a day and you get Coin Days Destroyed (CDD), a count that jumps when coins that sat still for years move again. A coin that sat for five years adds more than 1,800 coin days when it moves. A coin bought yesterday adds one.
Why is it a score from 0 to 100?
The daily count swings a lot, so it is averaged over about a month, and each day’s average is ranked against the four years before it. Near 100 is the busiest of those four years, near 0 the quietest. The record starts on 6 Jan 2013, the first day with four full years behind it. A day’s rank can change even when the amount of movement does not, because the four years it is measured against move on too.
What does it mean when old coins move?
When long-held coins stay still through a fall, their owners are not selling into it. When they move during a climb, it is often long-time owners taking profit, though a move alone cannot prove a sale. Busy spells have come both in climbs to new highs and in steep falls, so read the line beside the price.
What does the dollar view add?
Value Days Destroyed (VDD) weights each coin’s days by Bitcoin’s price on the day it moves, so it shows the dollar value behind the movement. It rises and falls with the price as well as with the coins: a high price makes ordinary movement look heavy, and a low price hides real movement. The plain count of coin days does not depend on the price.
Why count five years and more?
The old supply row counts coins that have sat still for five years or more. That is longer than the four years between halvings, so their owners have held through at least one full rise and fall. Some of those coins may be lost for good, and age alone cannot say which. See lost or sleeping coins.
Is every move a sale?
No. A move is a coin changing wallets. It can be a sale, a transfer between one owner’s own wallets, or an exchange shuffling the coins it holds for customers. That is why the page reads movement over weeks rather than single days. See how much of each age moved.

What does the current reading show?
Old-coin activity: the latest reading is 54.7, on . The highest reading since is 100 on ; the lowest is 0.1 on .
Daily readings since 6 Jan 2013, the first day with four full years of history behind it. Each ranks that day’s old-coin movement, averaged over about a month, against the four years before it, from 0 for the quietest to 100 for the busiest. Month-end values use the last reading on or before that date.
