When the total market capitalization of the crypto market reaches a new high, large - cap cryptocurrencies like Bitcoin and Ethereum may still dominate the market share, but there may also be an increase in the market share of some emerging and innovative cryptocurrencies. The trading activity may shift more towards high - growth potential coins. Conversely, when the market capitalization reaches a low, investors may flock back to more stable and large - cap cryptocurrencies, reducing the trading activity of small - cap coins.
