Is there a best day of the week to buy Bitcoin?
We dollar-cost-averaged $100 into Bitcoin every week since 2015 on each weekday. The best day (Thursday) beat the worst (Monday) by just 1.0% over the whole period — so the day of the week barely matters.
| Buying weekday | Average buy price | Value today |
|---|---|---|
| Monday | $1,746.65 | $2,776,993 |
| Tuesday | $1,744.24 | $2,780,834 |
| Wednesday | $1,730.04 | $2,803,653 |
| Thursday | $1,731.67 | $2,805,607 |
| Friday | $1,738.39 | $2,794,773 |
| Saturday | $1,739.15 | $2,793,553 |
| Sunday | $1,735.84 | $2,794,286 |
Method
For each weekday we invest $100 in Bitcoin every week from 2015 to September 2026 (about $60,900 in total) on that day only, using real daily closing prices (CoinGecko via cryptotools.tech/api (recent) + CryptoCompare histoday (history)). The gap between the best and worst weekday was just 1.0% over roughly eleven years — noise, not a strategy. Picking a “lucky” day doesn't beat simply buying consistently. Figures exclude fees and taxes and are not investment advice; past performance doesn't predict future results.
