Really, people are still using Bitcoin Doublers in 2017
It's probably the most stupid scam scheme. I expected that scammers become more inteligent and their schemes are more complicated.
And how much you are asking for this script (How much money scammer would have to rob money to get ROI from this purchase)? And I see you have other types of scam scripts of your site. That's bad. Instead of using your skills to make something good and useful, you will just help to loose hardly earned money for other people. I hope nobody will buy your scripts.
