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...
Never trade at new or problematic exchanges,never send your bitcoins to someone at first when you trade at first,never deposit any bitcoin into any sites without reading the KYC requirements.And use your mind most of the time you can save yourself from getting scammed.
