Bitcoin profitable days chart: the share of all past days on which BTC closed below today's price — 100% means every earlier buyer is in profit. Updated daily.
Left axis: BTC price (log). Right axis: share of past days that closed below that day's price (0–100%).
profitable days = days with close < today's close / all prior days
For each day, Coinfuty counts how many earlier daily closes were below that day's close and divides by the number of earlier days. The result is the share of Bitcoin's history on which a buyer would now be in profit — 100% only at a new all-time high.
The metric has never fallen below ~50% since 2013 because Bitcoin's early years were so cheap. It is most useful near the top: readings at 99.5% or above mean price is at or within a hair of its all-time high, and every cycle top by definition sat there.
92.3% of all days since 2010 closed below the Oct 19, 2026 close, so a buyer on any of those days is in profit.
Bitcoin traded under $1,000 for its first seven years, so most historical days are far below any modern price. The metric only becomes informative in its top few percent — readings near 100% mean price is at an all-time high.
On-chain metrics weight by coins moved on each day; this one weights every day equally and needs only price history, which is why Coinfuty can compute it for any coin.
Coinfuty computes every series on this page from daily BTC close prices and public constants — the Bitcoin halving schedule, block subsidy and published regression coefficients. Values refresh nightly (00:20 UTC) and the current day is patched hourly. These are historical, backward-looking indicators; nothing here is investment advice.
