Nearly three-quarters of cryptocurrencies that once entered the top 100 by market capitalization are now effectively inactive, underscoring how weak a signal valuation alone can be for long-term survival. CryptoRank said on August 10 that 71.9% of the 1,539 cryptocurrencies it analyzed had gone inactive under a definition of daily trading volume below $10,000 for 90 consecutive days and delisting from major exchanges. The platform said the average lifespan of a top-100 cryptocurrency was about two years and four months, and estimated that 62% of the current top 100 could stop operating within five years, rising to 84.7% within 10 years. The report said projects often disappear because they fail to attract users or withstand regulatory pressure and competition, while stalled development and weak liquidity can quickly erode demand. Experts said investors in lesser-known altcoins should look beyond market capitalization and assess trading volume, continuity of development, the actual user base, exchange listings and diversification.
