About over21m

I run a Bitcoin full node at home and maintain my own on-chain database. over21m is where I turn that raw data into charts about who is spending, at what profit or loss, across different coin age bands.

The focus here is on:

• UTXO age bands – from fresh coins to decade-old holdings
• Realized profit & loss at the moment coins move
• Long-term vs short-term holder behavior during big moves

I’m not trying to call tops or bottoms. I’m trying to answer questions like:

• Who actually sold into that dip?
• Are long-term holders distributing, or just letting newer buyers churn?
• Which parts of the supply are quietly accumulating in the background?

You can follow along on X at @over21m. This site will evolve as more charts and views go live.
