BITCOIN SUPPLY BY VINTAGE YEAR
Who still holds from each year?
Every Bitcoin is tagged by the year it last changed hands. Pick a year to see how many of its coins are still sitting, and what their owners paid.
How many Bitcoin still carry a last-moved date in 2025. A completed class only shrinks when its coins move, so a flat line is a generation sitting on its hands.

Is the Class of 2013 everyone who bought in 2013?
No, and that is why this page says last moved rather than bought. The chain records when each coin last changed hands, not who bought it first. A coin that moves today leaves its old year and joins this one, even if the same person still owns it. So an old class shrinking means its coins are moving on, and an old class holding steady means that generation genuinely has not touched its coins.
What does this mean for you?
The old classes are the market's memory: coins from 2013 still sitting have survived every crash since, and they rarely move. The young classes are its pulse. Watch whether the newest full year keeps its size, because a class that stops shrinking is a generation of owners settling in for the long haul.
Understanding Bitcoin Vintage Supply
Every coin carries a simple timestamp: the last time it moved. Group all coins by the calendar year of that move and you get vintages, the Class of 2013, the Class of 2021, and so on. A coin that moves today leaves its old class and joins this year's.
That is why "bought in" really means "last changed hands in". Coins still tagged 2013 have not moved for over a decade, so their owners have held through several complete market cycles. The size of each old class is a direct measure of how much conviction that generation still has.
The average price per class comes from the prices at which those coins last moved, not from anyone's original purchase. Dividing today's price by that average gives the class's profit multiple. The earliest years have no meaningful price, Bitcoin traded for fractions of a cent or nothing at all, so this page shows no multiple there rather than an invented number.
The pattern to watch is the recent years. Young classes are always the biggest, because coins churn. When a young class shrinks fast, its coins are moving on, either sold or settling into new hands. When it holds its size year after year, a new generation of patient holders is forming.
