I don't know if the market has regressed. In the past few days, several U.S. and Hong Kong stock brokerages have started to contact bloggers and communities in the crypto space, paying for advertising.
The main reason still comes from the increase in account openings in the crypto space, as some old-timers who used to play altcoins have started to play with Circle, SBET, and others.
It feels like the various micro-strategies for different cryptocurrencies have also intensified this phenomenon recently.
