As a newbie,what preventive measures should one have in place to make sure that their accounts are not defrauded or scammed?
Being scammed is a choice nowadays. So, it's not related to your account but to how you decide when you've seen some opportunities that are being offered to you.
Whether a newbie or not, no one is prone into being scammed unless you're an informed guy. So, with that I advise you not to take part into those people telling you that they have a money making opportunity to make.
Because if they know so, they won't be sharing it to anybody. What sense eh?
