People scam because they are desperate on money, usually they are that situation. But of course not all people are desperate on money scamming, but if they got chances to do it, most of them will.
Yeah it is true the people use to same because they are not having any kind of feeling they just want to increase the money and the wealth they are not having any concern with the humanity so it is the best timed buy the bitcoin and to hold till the price of the bitcoin will increase instead of the losing the money of the other people and giving them the chance to have the loss of bitcoin by the scamming.
True, they have no feeling they simply don't care about us. They steal the coins and put them on their wallet. Also they keep on doing it. Why are they no stopping ?
I think its because it is a fast way to earn money. Scammers need to be arrested and put in to the jail.
