The explosive growth of altcoin season is gone, and the reason is simple: it is due to the large-scale involvement of American Bitcoin funds, which has completely isolated the funds for Bitcoin and altcoins. In the past bull market, funds earned from selling Bitcoin could be quickly used to buy altcoins. Now, with various Bitcoin ETFs in the US, even if Bitcoin rises and profits are made, they are all cashed out in USD, with no other altcoin ETFs as options. Even Ethereum will not see large-scale inflows because only Bitcoin is recognized for its decentralization and limited supply, thus gaining acceptance from Wall Street funds. Since there is no new Wall Street funding, it will be difficult for this bull market to see a significant altcoin bull market.
