Method
We hold $10,000 in Bitcoin from 2015 to September 2026 (real daily closes, CoinGecko via cryptotools.tech/api (recent) + CryptoCompare histoday (history); 4,265 trading days) and, for each row, set the N biggest single-day gains to zero — as if you had been out of the market on exactly those days. A handful of explosive days carry most of the return, which is why trying to dodge the bad days (and missing the good ones) usually backfires. Figures exclude fees and taxes and are not investment advice; past performance doesn't predict future results.
