Survivorship Bias
Survivorship bias occurs when an analyst focuses only on the assets or strategies that currently exist or have succeeded while ignoring those that have failed or were delisted. In cryptocurrency, this is common when looking at historical performance data of tokens.
Many tokens that launched years ago have gone to zero or were abandoned by their developers. If you only analyze the tokens that are still trading on major exchanges today, you will get a skewed, overly optimistic view of historical returns.
This leads investors to overestimate the likelihood of success for new projects because they are not seeing the graveyard of failed protocols. It is a critical error in financial history and fundamental analysis.
By excluding failed assets from a dataset, the average performance appears significantly higher than it actually was for a typical participant. To avoid this, one must include delisted tokens and defunct protocols in any long-term performance study.
Ignoring these dead assets creates a dangerous illusion of safety and profitability in speculative markets.
