My classmates asked that question and the professor kept on talking about the probability of getting scammed but he's really against the whole crypto-currency movement so his opinion is biased.
So...here I am, asking for guidance...
Don't be surprised if you professor is biased and talking shit about crypto. Just let him be, but if I were your classmate I will definitely answer him.
Fiat do already involved on scamming, so we can really say that crypto market would still have that problem. If your prof will able to read up the usage or benefits
of crypto then he might really change his mind.
