The total number of Bitcoin currently in existence, approaching the fixed maximum of 21 million. Increases with each block reward. Currently approximately 19.7 million BTC.

Measures the 30-day net change in supply held by long-term holders. Positive = HODLers accumulating more than distributing. Negative = HODLers net distributing.
A visualization of Bitcoin's UTXO set age distribution over time. Shows what percentage of supply has been held for various time periods (< 1 day to 10+ years), creating colorful wave patterns.
The percentage of Bitcoin supply that has not moved on-chain for at least one year. Reflects long-term holder conviction and supply removed from active circulation.
The volume of previously dormant coins (held for 1+ years) that have moved on-chain. These are considered 'revived' as they break their dormancy to transact.
