Bitcoin DCA FAQ
Is DCA into Bitcoin a good idea?
Dollar-cost averaging spreads your entry price over time, so you never put everything in at a top, at the cost of giving up some upside when prices only rise. In this backtest $100 monthly since Jan 1, 2018 returned +394.2% against +496.1% for a lump sum on day one. Whether it suits you depends on your income, horizon and risk tolerance; this page is educational, not advice.
DCA or lump sum: which is better?
Historically a lump sum wins more often in rising markets because the money is exposed longer, while DCA wins when prices fall after the start date. The DCA vs lump sum panel above runs both for the window you chose, net of the same fee.
How are fees handled?
The exchange fee you enter is taken out of every purchase before coins are bought, so "total invested" is the gross amount you paid and "coins accumulated" reflects what the fee left. Recurring-buy fees on exchanges range from zero to about 1.5%; 0.5% is the default.
Where does the price data come from?
Coinucation stores a daily close for Bitcoin from Coinbase candles back to listing and CoinGecko for the last year, 4,099 days as of Oct 8, 2026. Today's value uses the price from our 20-minute sampler. Each purchase uses the close on its scheduled day; charts sample monthly.
What does annualised return mean here?
It is the money-weighted rate (an internal rate of return) that turns the sequence of purchases into today's value, so later purchases count for less time than early ones. It is an approximation and says nothing about future returns.
Calculations use monthly closes for charts and the daily close on each purchase date for totals. Past performance is not a forecast. Not investment advice. Ownership disclosure.
