Hey DanX88
                     Did you try and purchase a Giant B miner from this person?  (Male, female, humanoid, troll, dweeb, toilet trash, etc...)

                     Did they give you the run-around with delays in receiving the bitcoin?

                     Did they demand more money after your initial payment?

                     Did they threaten you with court for failure to pay additional money?

                     Did you use their alternative website selling page  Selly or did you deal with this person through personal emails?

                     I myself, attempted to purchase one for $6400 back on January 31th.

                     I am still trying to contact him through emails here and at his gmail account:  billydaakidd7@gmail.com 

                     I 'foolishly' still hope they are ethical and trustworthy and send the miner or refund my bitcoin.

                     Did you happen to get any personal information such as their name, address, phone number anything more concrete to contact them?

                     
                     Unfortunately, I have lots of questions regarding this person and their methods of 'scamming' their victims...
