Monthly $100 Bitcoin DCA since 2015 would be $632K
Coinbird finds $100 monthly Bitcoin DCA from Jan 2015–May 19, 2026 would have turned $13,700 into about $632,315 (8.219 BTC), a +4,515% return with a 76.72% max drawdown.
Coinbird analysis found that a $100 monthly investment in Bitcoin from January 2015 through May 19, 2026 would have turned $13,700 in contributions into about $632,315. The backtest shows the plan accumulated 8.219 BTC across 137 monthly purchases, a total return of 4,515% and a maximum drawdown of 76.72%.
The model calculated an average acquisition cost of roughly $1,667 per BTC, reflecting larger purchases at lower prices in the early years. Coinbird’s Bitcoin DCA Calculator used historical price data from CoinGecko for the simulation. The published calculations exclude taxes and trading fees.
The deepest decline in the backtest occurred during the 2022 bear market, when the portfolio hit the 76.72% maximum drawdown. The results state that recurring purchases do not remove price volatility or the potential for large interim losses.
Coinbird compared recurring purchases with lump-sum investments across multiple horizons. For an investor who began a $100/month plan in May 2021, the platform found DCA returned 84.34% from May 2021 to May 2026, turning $6,100 in contributions into about $11,244. A lump-sum investment of the same amount in May 2021 returned roughly 43% over the same period.
In Coinbird’s tested scenarios, lump-sum investing outperformed DCA at the one-, two-, three- and four-year marks. The five-year advantage for DCA appeared only after a full crash-and-recovery cycle.
Philipp, founder of Coinbird, commented: “The interesting finding is not simply that Bitcoin went up since 2015. In this historical scenario, automatic monthly buying through crashes, all-time highs and regulatory uncertainty still produced extraordinary long-term results. At the same time, the drawdowns show why this strategy is much harder to live through than it looks on a chart in hindsight.”
