It is quick money if they scam they don't have to work hard for legal money thats why they do it. They want fast money as soon as possible so they scam with it.
There a lot of scammers with bitcoin so you should be alert they want all of your coin.
I know a lot of my friends that got into scam business. Most of them are very stupid to the extent they believe that scam is not an evil thing. They always say that scamming is better than killing people, so that you should scam than kill.
But all these things are the same and is punishable by the law if you found getting involved in such. Most of them are hardened criminals and you just have to avoid them.
That's true enough but the issue about scamming is it's hard to trace who's person is doing the scam thing to others. We always check our phones or computers because of important emails and so on we have difficulties in people who send us many emails without any prior information for us. It is through advertisements that pops out suddenly and the rest becomes history if we convey with them. That's why people scam because they easily believe on something and if it is really catchy strategy.
