Bitcoin's 4-Year Cycle and the Risk of a Self-Fulfilling Crash

Bitcoin's halving events-programmed reductions in block rewards for miners-have long been framed as catalysts for cyclical price trends. Historically, these events have triggered surges in demand due to reduced supply, reinforcing the narrative of Bitcoin as a . However, as the cryptocurrency enters a new phase post-2024 halving, the interplay between market psychology and structural supply dynamics raises critical questions for long-term investors. This article examines the validity of the 4-year cycle theory, the psychological triggers that amplify volatility, and strategies to mitigate risks in an increasingly speculative market.

The 2024 halving demonstrated that market dynamics are evolving-corrections are less abrupt, and institutional adoption is reshaping investor behavior. For long-term holders, the priority must be to adopt disciplined while remaining cognizant of the self-fulfilling nature of market expectations.
