its perfectly reasonable to be skeptical,more`s the point,its an imperative.i think we are all aware that scammers are everywhere,paid shills too.their methods are well known,they are very motivated,rigorous and dedicated in their highly evolved schemes.do as much research as you can,which can take time.there are videos on youtube and google(frightening) which should be required viewing.the acid test is trying yourself.ive been ripped off before,years ago,not a good feeling.best of luck guys.
