Fraud is now at every turn. every time you receive an e-mail, there is a thought, not whether it is scammers. When your friend writes to you on the social network "friend, urgently lend me $50", you think, instead of swindlers whether it. Deception is everywhere, everyone lies to each other, and you're always afraid of getting caught in someone's trap. That's bad! But there is no fault of the cryptocurrency sphere.
