The real question is : How they will cash out. With this strategy, they just want to have a control of all the coins and after they will disappear  with all your money.
Don't trust promises and even more when you have no way to find them after they will decide to screw people.
In this kind of scam, the first ones will be served first and for the others, you will have enough satoshi to buy you some tissues to dry your tears.
Again, Santa close does not exist.
