Selling by some early investors and founders of various projects appears to be triggering a "crypto winter" for "altcoins." CoinMarketCap data shows that since the peak of Bitcoin prices in March this year, the market value of altcoins (that is, tokens other than Bitcoin, Ethereum or stablecoins) has fallen by nearly 30%, while Bitcoin still accounts for more than 50% of the estimated $2.4 trillion digital asset market. This year, the tokens of many projects began to "unlock", allowing venture capitalists and founders to sell digital assets acquired early. (Bloomberg)
