Why is the SEC so slow to regulate cryptoassets? Literally everything that they combatted for stocks and traditional assets is now taking place in the crypto ecosystem.
Because they are a gutted, disempowered US-regulator. Wrecked by 4 years of Trump and countless other presidents before them. Possibly there is also not the political will to ramp up the regulatory speed and power although I still have hope that Biden will be able to change that at least a bit.
Look at the suggested reforms the SEC was supposed to undertake AS IDENTIFIED BY CONGRESS. Then look at what actual reforms where implemented.
I'll help you out - almost none. The SEC has had a monopoly on financial market regulation since the 1930s and is just now becoming a victim to the cultural side affects of this monopoly. Shit, I actually think the SEC has done a phenomenal job regarding this and all other aspects of their job.
