Have you ever calculated how many times you have to claim to reach that minimum withdraw threshold? It will take you months and by that time site might run away and even though if you will manage to request withdrawal from them they might simply refuse your request because they are not earning any bitcoin from their operation other than paid membership they are selling. So when there will be no new fools to invest on those shitty packages site will simply shut down and owner gonna fly away with whatever he have in the wallet.

Stay away from such scams.
