If Bitcoin follows the path of history repeating itself, the next correction target price is $48k.

Bitcoin has always fallen below the 61.8% Fibonacci retracement line from its starting point during every bear market since 2010.
If this pattern repeats, BTC's price could drop approximately 26% from the current $65k, down to around $48k.

• How is Fibonacci retracement calculated?
• Target price for this cycle: $48k
• An overlooked blind spot: insufficient sample size

Bitcoin's price movement hides a pattern spanning 16 years of history: after each bull market peak, the bear market always falls below the 61.8% Fibonacci retracement line from the starting point in 2010, with no exceptions.

If this pattern continues in this cycle, Bitcoin could retrace from the current $65k down to about $48k. Based on the current price, that’s roughly a 26% decline.

How is Fibonacci retracement calculated?

Fibonacci retracement is one of the most commonly used tools in technical analysis, derived from the proportional relationships in the Fibonacci sequence. The 61.8% level (the inverse of the golden ratio φ) is considered a key support and resistance level.

The algorithm for this pattern is simple: starting from Bitcoin’s trading price of $0.003 in February 2010, draw Fibonacci retracement lines up to the peaks of each bull cycle. The movement over the past four cycles is as follows:

• June 2011: First bull market peak → subsequent bear market breaks below the 61.8% retracement line
• November 2013: Second bull market peak → bear market again breaks below 61.8%
• December 2017: Third bull market peak → bear market breaks below 61.8%
• November 2021: Fourth bull market peak → bear market again breaks below 61.8%

Four bull markets, four bear markets, four breaks, with no exceptions. CoinDesk’s charts show that each bear market low was below the 61.8% retracement line, not above it.

Target price for this cycle: $48k

Bitcoin reached a new all-time high of $126k in October 2025 during this cycle. Using $0.003 as the starting point and $126k as the peak, the 61.8% retracement level is at $48,215.

Currently, Bitcoin’s price is about $65.5k, still some distance from that target. In other words, the pattern has not yet triggered, but once it does, the price could head below $48k.

An overlooked blind spot: insufficient sample size

Four cycles are still a small sample size statistically. More critically, today’s Bitcoin market is vastly different from ten years ago.

The current market structure is dominated by ETFs, with institutional funds providing major liquidity, and derivatives strategies far more advanced than before. This market maturity might cause prices to find support before reaching the 61.8% retracement line, meaning the pattern could “fail early” in this cycle.

However, for technical analysts, $48,215 remains a key lower reference point. Especially since Bitcoin has fallen nearly 49% from its $126k all-time high (as of June 8 data), the market sentiment is approaching the lowest levels since the 2022 bear market.

For Taiwanese investors, Fibonacci retracement offers not prophecy but a risk management framework. If you have positions above $70k, the $48k target provides about a 30% buffer, which is still reasonable at this stage.
