According to CoinMeta, as reported by Grayscale, Bitcoin has only accounted for about 30%-46% of the return variations in the six cryptocurrency sectors over the past three years. The report indicates that as the volatility of AI tokens reaches 85%, the crypto market is becoming increasingly diversified. Grayscale found that the financial and utilities sectors have the weakest dependence on Bitcoin, with only about 30% of return variations explained by Bitcoin. The artificial intelligence sector accounts for 35%, smart contract platforms for 38%, and currency assets for 43%. Despite this decrease in correlation, Grayscale warns that diversification does not necessarily mean a reduction in risk. Bitcoin's annualized volatility has dropped to about 43%, compared to 81% five years ago. The volatility of all cryptocurrency sectors studied is higher than that of Bitcoin.
