according to Assemble AI, Coinbase's report predicts that September will see a significant season of altcoins as Bitcoin's dominance declines. The report notes that Bitcoin's market share has dropped from 65% to 59%, and early signals of funds rotating to altcoins have been observed. Despite the current altcoin season index being only 40, well below the threshold of 75, Coinbase remains optimistic due to the expected increase in liquidity.
