Heads up, I saw on Twitter yesterday that Coinomi successfully contacted NameCheap and got them to take down a scam website. Since mybtgwallet.com is also registered at NameCheap, I contacted them and they had me open a ticket with their legal department. I asked for the site to be reviewed/taken down and pointed them to this thread for details.
We'll see what happens. No chance we'll get our funds back but at least we might put a stop to it.
