i really can't believe that people pay attation to such a money multiply game.
unbelivable

lets say, i can do the same with cars!
still give my your car. later i will give you 10 cars.
i can do that because i search security issues on parking decks...
do you belive me?
yeah, and do you have a idea why i need your car?


by the way, both sites don't proviede a secure internet connection!
no HTTPS link !!!
very trustfully....
