Scammers are everywhere here in the virtual world, it can't be help since they have guts to scam people because we all are anonymous in the cryptocurrency world, unless you're going to provide your personal information (which is not recommended). And when you got scammed once, please let it be your lesson, don't let it happen again. Before you make a transaction with someone, make sure he is a legit one, try to have an escrow or ask him a proof of his legitimacy and so on.
