Overview​

2011-2013 Cycle (ATH) tracks Bitcoin's price as an index starting from the all-time high on June 11, 2011 ($35.88). Values below 1.0 represent the drawdown from the peak, while crossing back above 1.0 marks the recovery to and surpassing of the previous ATH. This was the first complete ATH-to-ATH cycle in Bitcoin's history.

Formula​

Index(t)=Price(t)Price(2011-06-11)\text{Index}(t) = \frac{\text{Price}(t)}{\text{Price}(\text{2011-06-11})}

Interpretation​

  • Dropped to approximately 0.06, representing a 94% drawdown — the deepest bear market in Bitcoin history
  • The low was reached in November 2011, just 5 months after the ATH
  • Recovery took about 18 months to reclaim the previous ATH
  • Eventually reached 32x the starting ATH by late November 2013, demonstrating Bitcoin's ability to recover from extreme drawdowns

Use Cases​

  • Drawdown analysis: The deepest bear market in BTC history (94%) provides context for all subsequent drawdowns
  • Recovery timing: Establishes the earliest reference point for how long ATH recovery takes
  • Historical context: First complete ATH-to-ATH cycle shows the most extreme version of the boom-bust pattern
