They are 100% scammers!
One of my friends was scammed 2 times by these "gambling experts"
The bad part is I was involved in this (I helped my friend with the hosting and negociated, communicated and pay to BitBox in his name).
I will post an update soon with all the proofs to show that they are ordinary scammers!
I too have all the proofs.. I don't know where to post. Is there any thread where we can place reports about this scam?
