BTC hits the 90,000 yuan mark, but not many people are really happy because most people can't afford BTC and they all have altcoin in their hands. Currently, the market data shows that BTC is performing on its own, while altcoins are stagnant, including leading altcoins such as Ether, whose gains are far behind BTC. Why is there such a divergence? Will there be an alt season? The divergence is caused by the concentration of funds within the industry. After the approval of ETF, more market maker institutions will enter the crypto market, and they only recognize BTC as the leader, which is caused by the concentration of funds within the industry.
