It is a nice story. Scams are always there because there are people who likes to get easy money and are greedy. Just often think about this to avoid scams. When you say people promising you something especially about earning money. Always try to be negative on it. Why? Understand that a person is wanting you to become rich. If it is true he would have not attempted to encourage you because he himself would have taken the opportunity. This is comparable to a person who have just found a box of treasure. Do you think that person will tell you about the treasure? Certainly not. Nobody would tell you to pick it up for him for the fear that others might get it before him. So it would be a scam because he would have done it himself it it was true.
