About this metric
What it measures
Supply Last Active 2y–3y measures the BTC in unspent outputs last moved on-chain between two and three years ago. It tracks a rolling one-year segment of multi-year supply, with coins entering at two years of age and leaving when spent or when they reach three years.
How to read it
A thickening band records a wave of outputs surviving beyond two years; it can preserve the footprint of activity from an earlier market phase. The series peaked near 3.19 million BTC on November 1, 2023. During 2024 its balance ranged from about 2.78 million to 1.38 million BTC, illustrating how much a rolling older cohort can change.
Shrinking supply does not establish reactivation, because coins reaching three years migrate into 3y–5y without moving. Lost keys and deliberate holding look alike until a spend occurs, while self-transfers restart age without proving a sale. Follow several adjacent bands to judge the durability of older supply rather than interpreting this one band in isolation.

FAQ
Why is the 2y–3y series zero at the start of Bitcoin's history?
No output could reach two years of age during the network's first two years. The early zeros reflect an age constraint, not an absence of willingness to hold.
What does the November 2023 peak show?
About 3.19 million BTC had last moved two to three years earlier and remained unspent on November 1, 2023. It shows the size of that surviving age cohort, not the amount purchased or withdrawn from exchanges on that date.
Is 2y–3y supply a count of coins waking up after two years?
No. It counts coins still unspent in that age range. Measuring reactivation requires data on spent outputs and their previous ages, rather than a balance of dormant outputs.
