Smart investors adjust strategy during bear markets and large drawdowns like Bitcoin’s recent 50% drop. Dollar-cost averaging (DCA) — investing a fixed amount at regular intervals regardless of price — is a common approach that smooths entry timing and builds exposure over time. Historical cycles and forward-looking BTC simulations help illustrate how steady purchases perform across different starting points and horizons.
A five-year DCA stack shows sizeable net gains
A $250 weekly Bitcoin purchase beginning January 2021 totals $67,500 invested over five years. According to DCA simulation data, that plan accumulated 1.65097905 BTC at an average buy price of $40,884. At a Bitcoin price near $71,000, the holdings are worth about $120,518, a $53,018 gain (76%) on invested capital. At $100,000 BTC the same stack would be worth roughly $165,098, and at the October 2025 cycle peak near $126,000 it would reach about $208,023.
A shorter accumulation window shows how entry timing affects early outcomes while the strategy continues building exposure. A $250 weekly DCA beginning January 2024 invests $28,500 and accumulates 0.36863166 BTC at an average price of $77,312. At $71,000 that position is worth roughly $26,909 (about a 6% unrealized loss). At $100,000 it would be $36,863, and at $126,000 roughly $46,448.
Comparisons with equities reinforce DCA’s historical edge in volatile markets. Swan Bitcoin analyst Adam Livingston showed that $100 weekly over five years produced $42,508 in Bitcoin versus $37,470 in the S&P 500, equating to returns of 62.9% and 43.6% respectively. Consistent purchases through drawdowns have historically yielded stronger cumulative returns in BTC despite higher volatility.
Long-term models emphasize time horizon
Forward-looking simulations explore DCA from 2026 onward. A $250 weekly DCA starting January 2026 would put about $54,250 to work by March 2030. Price assumptions in many models follow Bitcoin’s long-term power-law growth curve, which maps historical price versus time on a logarithmic scale and produces a rising support band and median trend that have broadly matched prior cycles.
Using that framework, some analysts expect long-term trend support to move above $100,000 by 2028. Bitcoin Well’s simulations place the median near $430,278 by March 2030, with a lower projection around $274,000 and an upper scenario near $900,000. Under those assumptions the weekly $250 DCA accumulates roughly 0.30 BTC over four years, producing estimated values by March 2030 of:
– ~$82,200 at $274,000 BTC
– ~$129,000 at the $430,278 median
– ~ $270,000 at $900,000 BTC
A November 2025 study by researcher Sminston With tested entry timing against similar long-term projections and found that even buying 20% above a then-price of $94,000 and exiting 20% below the projected 2035 median still yielded nearly 300% gains on remaining holdings after a decade. Total simulated savings reached 7.7 times initial capital. The study concluded that while entry timing alters outcome ranges, long holding periods account for the majority of returns.
This evidence underscores how regular, disciplined buying across bull and bear phases can steadily accumulate BTC exposure and deliver strong long-term results, especially when paired with multi-year holding horizons.
