I am sorry but you get scammed, as already stated in this topic. normally there is not an honest ponzi. all are just created to stole your funds.
so you play only at your risk, and is a great risk, because btc is every day more precious and more rare, then yesterday.
you have learned 2 lessons: no one give money for free, all ponzi /hyip are just a waste of time
