The professor is not wrong at all, however, we all heard this arguments already. And so far despite the negative connotation and whatever authorities like SEC has given us the warnings, people are still flocking in the market.
And with that and in the last 10 years or so, despite the negativity that comes with crypto investment, I don't think that it's going to slow down in the next decade and on the contrary, we might hit numbers in terms of crypto investors. We could also say that despite the red flags from this so called professor and experts on finance and economics, crypto will move forward and no one can stop it.
