The calculation methods of crypto industry indices are generally scientific, often weighted by market cap or trading volume. However, they need adjustments as markets evolve—e.g., excluding illiquid tokens or adding new sectors. Adjustments enhance accuracy by reflecting real - time market structures. This improves the reliability of trend analysis, as outdated indices might mislead due to skewed weightings. Regular tweaks ensure indices remain relevant, aiding investors in making informed decisions amid dynamic crypto landscapes.
