According to CoinMeta, as monitored by cryptorank, in 2026, excluding stablecoins, the top seven cryptocurrencies (MAG7) accounted for 92.1% of the total market value of the top 100 largest crypto assets, with the market value concentration returning to levels seen in 2021. Among them, Bitcoin alone accounted for 66.6%, which is significantly higher than five years ago. This data indicates that market growth is increasingly dependent on a few large assets, while the broader altcoin market attracts a relatively smaller proportion of funds.
