Hello,
today I want to intodruce something that calls himself a Bitcoin Matrix. BTCFlood.

You have only to invest once 0.04 BTC and get through this matrix up to 16 BTC.
All you need to do is to invest the amount and get 2 Refferals to do the same, in order to achieve higher levels, up to level 4. So you can really earn 16 Bitcoin in a month.
Only 2 Refferals are needed, because you get automattically new refferals after upgrading to level 2 on autopilot.
