As wrote this is a temporaney script bought.
Here is the proof:

We modified it

Hi guys we are excited to present our new site BtcJack.xyz
We bought a temporaney script just to test the things but we are building our.
Our system give you the canche to multiply your investiment of 20% after two days (for a total of 120%).

Are you a ponzi scheme?

We are not using a ponzi scheme.
We use 2 things to multiply your money:
1) We made trade on 1broker.com
2) We earn money from ads (as you can see)

Investiment type:
We are new so without lot client and now we can afford only 120% after 2 days to not reach bankruptcy, in future if all will go well we will add new long investiment type and cloudmining(1% of possibility that will do this but...)

Min and Max investiment:

We require a minium of 0.001 bitcoin to multiply it, and we not have a max but we would recomend 0.2 or 0.3 max

Refferals:
We give 10% from your friends investiments.

Payout:

Once you reach your 48 hours your payment will say "pending" this because we have disabled automatic payment to check the system, we made it manual within 48 hours from "pending".
