Many of them who are scamming its for them easy to make money with it thats why they are doing it. My friends all got scammed with using bitcoins scammers have now a paradise.
Because they can steal their money and the coins are now for them you can't get them back.
Each and everyone of us needs money to change our lifestyles and way of living. People who made bad doings like scamming in socialmedia in order to excel or being selfish, they do what ever it takes to take advantage of everybody.
Much better to aware those scammer people around the social media, since we cannot control those people and safety first l, all the time to last detail of your account.
