Introduction
Bitcoin has historically followed a four-year cycle, a combination of mining economics and investor behavioral psychology. This cycle was previously driven by the Bitcoin halving event every four years, which reduces the supply of new Bitcoin and increases mining difficulty, in turn leading to price appreciation. However, as the Bitcoin market evolves, a new cycle appears to be emerging, a two-year cycle driven by fund manager economics and the behavioral psychology induced by ETF flows.
The Past Cycle: Halving and Herd Behavior
Historically, the four-year halving event was the primary driver of the cycle. This halving reduced new supply and squeezed miner profitability, forcing weaker players out of the market and reducing selling pressure. This subsequently drove up the marginal cost of new Bitcoin, resulting in a slow but structural supply squeeze. This created a psychological feedback loop driven by investors betting on this anticipated event, leading to price increases, media coverage, and retail investor FOMO.
The Shift to a Two-Year Cycle: Fund Manager Economics
With the introduction of ETFs, the dynamics of the Bitcoin market have changed. This article proposes that Bitcoin will follow a two-year cycle driven by the mindset of fund managers and the impact of ETF flows. This proposition is based on three key assumptions:
- Investors are evaluating their Bitcoin investments on a one-to-two-year timeframe, typical for asset managers in liquid funds.
- Fund flows from professional investors via ETFs dominate Bitcoin liquidity.
- The selling behavior of legacy whales remains constant and doesn't influence the analysis.
Factors Influencing Capital Flows
Several crucial factors influence capital flows in asset management. These include co-holder risk and year-to-date performance. Co-holder risk refers to the fear that everyone is holding the same asset, which can exacerbate potential market moves when liquidity is unidirectional. Year-to-date performance is also important because fund fees are based on annual performance on December 31st. This makes fund managers more sensitive to selling their riskiest positions near the end of the year if they don't have enough locked-in profits to cover potential losses.
How Fund Managers Evaluate Bitcoin Positions
Fund managers are likely to argue to their investment committees that Bitcoin has an annual compound growth rate of around 25%, thus requiring a compound growth of over 50% within a two-year timeframe. If Bitcoin goes up 100% in one year, that's great. However, if Bitcoin is down 7% year-to-date the following year, that's not so great. These investors now need to make over 80% in the next year or 50% in the next two years to hit their targets.
The Impact of ETF Flows on Bitcoin's Price
Bitcoin's price is now near $84,000, the total cost basis of all ETF flows since inception. However, most of the gains are from 2024, with almost all ETF flows in 2025 being in the red. Given that the largest monthly inflows were in October 2024 when Bitcoin's price was already high at $70,000, it could lead to a bearish pattern. Investors who invested heavily in late 2024, and who haven't yet hit their return threshold, will face a decision node as their two-year period approaches. Those who invested in 2025 will need a strong 2026 to make up for their losses.
Conclusions
The four-year cycle is no longer relevant, but that doesn't mean that there are no new cycles. Those who understand this specific behavioral psychology will find a new workable cycle. This will be more difficult because it requires a more dynamic understanding of capital flows in the context of cost basis rules. However, it will ultimately reaffirm the truth about Bitcoin: it will always fluctuate based on marginal demand versus marginal supply and profit-taking behavior. It's just that the buyers have changed, and the supply itself has become less important. The good news is that these buyers, who are proxies for other people's money, are more predictable, and less important supply constraints mean that the more predictable things will become the dominant factor.
