Cost Basis by Age
How cheap did long-time holders buy in?
Drag through the holding ages to see what each group paid, on average — older coins were bought far cheaper.
Almost every Bitcoin that's been held more than a few months is now worth more than its owner paid for it — only the most recent buyers are still underwater.

Understanding Cost Basis by Age
Every Bitcoin on the blockchain carries a record of the price it last changed hands at. Group coins by how long they've been sitting still — held more than a month, more than a year, more than a decade — and average the price each group last paid. That average is what they paid: their cost basis.
Older coins almost always paid less. Someone whose coins haven't moved in ten years bought when Bitcoin cost a few hundred dollars; someone whose coins last moved a month ago paid close to today's price. So the line slopes down steeply as you drag toward the older groups — that downward slope is the whole story of Bitcoin's rise.
The useful question is where the line crosses today's price. Every group below that line is in profit; everyone above it is underwater. In a strong market almost every group is in profit and only the newest buyers are below water. When price falls, the breakeven point creeps toward the older, more patient groups — and that's an early warning sign worth watching.
Why it matters: the oldest groups paid so little that they almost never sell at a loss, which makes them a steady floor under the market. The newest buyers are the opposite — they're the most likely to panic when price dips below what they paid. Watching which groups are underwater tells you where selling pressure is most likely to come from.
These numbers are read straight from the blockchain, not modeled or predicted. Each group's figure is the real average price its coins last moved at, updated as the chain settles each day.
