I know that most bitcoin "multipliers" are complete scams however this one is different.
I am not claiming to double your money.
I am not claiming to tripple your money.
I am claiming to increase your money.
Here is how.
I run a Dark Net buissness that gets me a lot of profit.I use the bitcoins you invest to pay for my products,
then you get your money back + some of the profit I made from selling the item.
You send me bitcoin -> I buy and sell product with your bitcoin -> you get your bitcoin back and some profit from the sale.
