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...
If you really don't want to be scammed by other people in crypto then you should try to learn the basics about it. It is all about common sense and the scammer are pretty obvious here. And especially, don't chase money.
Scammers are everywhere at any time. You cant hide yourself from them. And right now they are so easily getting contacts of people. So yes, keep implementing best practices for safety.
