Bitcoin's predictable four-year cycle is quietly making dollar-cost averaging (DCA) a more expensive habit than most investors realize, according to a fresh analysis circulated to financial advisors this week. The report argues that blindly buying Bitcoin at regular intervals — a strategy long sold as a safe harbor from volatility — actually drags down returns over a full cycle, and recommends a more deliberate, cycle-aware approach instead.
Why DCA falls short in a cyclical market
The logic behind DCA is simple: by investing a fixed amount at regular intervals, you smooth out price swings and avoid the risk of buying at the top. But Bitcoin's price doesn't move randomly. It follows a roughly four-year rhythm tied to halving events — supply cuts that historically trigger a bull run, followed by a bear market. The analysis notes that anyone who DCA'd straight through the 2021 peak and the 2022-2023 downturn ended up buying a lot of expensive Bitcoin near the top and only a little at the bottom, because the dollar amount is fixed regardless of price. That lopsided weighting pushes the average cost basis higher than if you'd simply waited for the post-halving low.
What a cycle-smart strategy looks like
The alternative, dubbed a cycle-smart strategy, essentially front-loads purchases during the bear-market trough and scales back as the bull run matures. Advisors are being told to use on-chain data and historical price patterns to identify the window roughly six to twelve months after a halving — when the market tends to bottom — and concentrate larger buys there. The approach does not call for market timing in the day-trader sense, but rather a disciplined, macro-level allocation shift that mirrors the actual rhythm of the asset. The analysis shows that even a simple rule — buy twice as much in the 18 months following a halving as in the 18 months before — outperforms steady DCA over multiple cycles.
The timing of the report matters. Bitcoin's current cycle entered its post-halving phase in April 2024, and the market has been grinding higher through 2025 and into 2026. Advisors who stuck with DCA through the 2024 low may have done okay, but those who are still DCA'ing into the current elevated prices are effectively locking in a higher cost basis just as the next bear phase could be approaching. The report urges advisors to review their clients' Bitcoin cost bases and consider pausing or scaling back DCA until the next cycle low emerges — likely sometime in 2027 or early 2028.
No specific firm or analyst is named in the document, but it's being circulated among registered investment advisors in the U.S. and Europe. The next concrete step for advisors: backtest the cycle-smart approach against their own client portfolios before the next halving in 2028.
