Bitcoin Is at a Cycle Crossroads: Is the 4-Year Rule Still Valid or Have the Bears Started?

Hello everyone,
The crypto market always has a way of making us feel familiar but never exactly the same. With each cycle, the community reminds us of Bitcoin’s “four-year rule” – halving occurs, supply decreases, expectations rise, capital flows in, and a strong growth cycle forms. Then comes the prolonged adjustment phase.
Looking back at history, the three previous major growth cycles of Bitcoin all lasted around 1060–1140 days. The rhythm is quite clear: nearly three years of growth, followed by about a year of adjustment. It is this repetition that leads many to believe that the market operates according to a relatively stable “pattern.”
But the problem is: the current cycle is approaching that timeframe.
If we count from the most recent bottom, the upward trend has lasted over 1000 days. If history continues to repeat itself, we are in a sensitive zone – where the risk of adjustment is gradually increasing. But if the market has not yet reached its peak and still has room to rise for a few more hundred days, it means that the cycle structure has changed. And when the structure changes, our approach to the market must also change accordingly.
So what is the more likely scenario?
The reality is that the market never perfectly replicates the past. Each cycle has its own context: institutional capital flows, ETFs, monetary policy, global acceptance levels… These factors can lengthen or shorten cycles. Therefore, clinging tightly to the number “4 years” while ignoring real signals is a mistake. Conversely, completely dismissing historical data is also unwise.
At the current stage, the most important thing is not to predict the exact peak or bottom, but to maintain awareness. If you believe the cycle is still in effect, be prepared for the possibility of strong volatility and deep adjustments. If you think the market has entered a new era, understand that old strategies may no longer be suitable.
In investing, extremism is always the greatest enemy. Being too optimistic can lead us to become complacent, while being too fearful can cause us to miss opportunities. The market at a crossroads is not for us to “bet,” but for us to observe more closely, manage capital more tightly, and be more flexible in our strategies.
Cycles can change. But the principles of risk management and discipline are never outdated.
Always remember: learning and enhancing awareness is the most sustainable asset in this market.
