Bitcoin market share rises to a new high in nearly four years Today, Bitcoin's market share rose to 64.61%, reaching a new high since February 2021. The high market share of Bitcoin indicates the silence of the counterfeit market, but it also represents the imminent bottoming out and rebound. When Bitcoin's market share surged to 60% in November last year, altcoins launched a small bull market. In both 2019 and 2021, Bitcoin's market share reached a high of 70%, followed by a magnificent general rise.
