BitMiner Pro is a total scam. They have ripped of numerous people in regards to getting into the mining of coin. Made promises that they never kept and had excuses at every step of the way. They are known for other scams such as Cobra Mailer that also took peoples money and never delivered. In regards to the Bit Coin mining and miners I have contacted every Federal agency about their scam along with the States Attorneys office in Missouri where Luke Sample is located. That is also the location of the supposed miners that they sold many people.
There is a very good video on youtube in regards to the issue with them scamming people for Bit Coin Miners. Another person name Gary Maroane made the video : https://youtu.be/HzUGJvsmRzo
