In my opinion, you should be prepared psychologically.
Confidential: With buyers and sellers, you sometimes know each other in real money buying mode, but when trading with Bitcoin they do not know what. Things are not absolutely secure: Everything has two sides of it, when everything is anonymous, high-tech crime will begin to develop in every way to rob things in your hands.
if you're afraid of tech crimes, you have to strengthen your account security. and you have to choose a trusted exchange for the exchange of your assets.
