Bitcoin's dominance in the crypto market remains strong, delaying the anticipated altcoin season, according to a recent analysis by crypto service provider Matrixport. Currently, Bitcoin's market share stands at 58%, despite the existence of over 20,000 other cryptocurrencies. The analysis attributes this dominance to several factors, including the large inflow of funds into Bitcoin spot ETFs and the limited participation of individual investors in the market. Furthermore, the surge in Bitcoin's trading volume is expected to further solidify its dominance.
