I think that's not how this game works. It was not like a money doubler scheme but anyone can donate on the address and once they reach a certain amount it will then be send randomly to another bitcoin address. The ones that receives it is going to be lucky because they just got free money but that is if the address is valid and it's actively owned by someone else.

I am only afraid that what if they sent the amount to a dead address or to a non-existing address? The money will be gone then but before that, this game should only be done by the trusted people so that we are sure that they won't pocket the money for their own good.
