Key Takeaways

  • Bitcoin (BTC) has been approaching four years since its all-time high.
  • The two cycles before lasted roughly four years, measuring from the previous high.
  • Will the same happen this time, leading to a cycle peak in November 2025?

The Bitcoin price has fallen since its $124,474 all-time high on Aug. 14, and trades 9% below its high today.

Since the previous Bitcoin cycle ended in November 2021, proponents of the 4-year cycle believe that the top is near, even though on-chain indicator signals suggest this is not the case.

To gain clarity, let’s review a few key charts and compare Bitcoin’s current performance with past cycles to see if this one will end in four years.

Bitcoin’s Cycle Comparison

Even with unusual bouts of volatility and extended consolidation, Bitcoin’s trajectory since the last low remains strikingly similar to earlier cycles.

If history repeats, BTC will see another push higher in the next few months before reaching its cycle top.

The 2015 to 2018 cycle (blue) had a parabolic increase in its last few months before a massive correction.

The 2018 to 2022 cycle (green) was more gradual, since the price created a double top pattern before declining.

That suggests the cycle high could arrive between October and November 2025.

However, the exact price target remains uncertain, depending on whether the cycle will be more similar to the 2015-2018 or 2018-2022 ones.

Comparing to the 2021 Cycle

The price action and momentum indicator readings are similar to the Bitcoin cycle that ended in 2021.

There are two main reasons for this.

Firstly, the BTC price created a double top pattern when the second high was higher than the first one, with a correction lasting several months in between.

Secondly, the RSI and MACD generated bearish divergences near the tops, confirming the weakness during the second high.

Shortly after the high, an RSI cross below 50 and a bearish cross in the MACD occurred, confirming that the trend is bearish.

The divergences are present in the current movement, but the indicators have yet to cross below their bearish thresholds.

Since they are declining, it could be several months until they do, confirming the cycle top.

Compared to the 2017 Cycle

The cycle that ended in 2017 is extremely dissimilar because of its rate of increase and lack of weakness near the top.

At the time, the price of Bitcoin had increased parabolically for nearly a year before the cycle top.

Additionally, the three monthly candlesticks leading up to the top were bullish.

Another difference is the monthly RSI, which hit 90 during the high and had no bearish divergence.

The RSI is at 71 and has already generated a bearish divergence.

As a result, the two cycles are so dissimilar that it does not seem likely the current one will follow the 2017 one.

To do so, Bitcoin would have to go on a parabolic run well above $200,000, bringing its RSI near its all-time high.

Bitcoin’s 4-Year Cycle

Bitcoin’s current cycle is more similar to the one that ended in 2021 than the one that ended in 2017. 

The resemblance comes from its steadier pace of growth, lack of parabolic surges, and familiar signs of weakening momentum near the top.

If history is any guide, Bitcoin’s cycle peak will likely arrive in October or November, only incrementally higher than today’s price levels.

Alternatively, Bitcoin could do away with the four-year cycles altogether and continue increasing well into 2026 and 2027.
