Many good points in this article.
I doubt a ban on cryptos would happen as many of these regulators and politicians are probably already invested in the space.
If they decided to do draconian ban, the backlash from their constituency will be quite severe. I think it's too late for a ban as there is already too much VC money invested in various crypto startups, and those VCs have lobbyists.
The one thing that bother me about ETH going into POS is that nobody knows what the long-term inflation rate is going to look like! Secondly, how would Vitalk and/or the foundation know what the best course of action in determining this variable? BIG question right there.
