Yes, this is a very attractive opportunity for investors. It is possible that this will be the "killer-feature" of the project.
This cant be deemed a feature. The idea here is very simple, a stranger calls u and asks to join buying action under the condition that u will be paid later by someone else is now presumably hiding inside ur house. U go buy a coin and check the home to find out who is ur benefactor. It appears that u were duped and u are alone in ur home hence no pay for u.
I do not quite understand what you mean. Everywhere there are certain risks. The most important thing is that the expected profit covers these risks, anyway each investor must make a decision on his own.
