Soft4cash.net Totally lied to me .waited until i made the $300 payment in btc and then went dark. California!!. They offer adder software. Its ethical by the process in which the extra nominations are added. Mined thru their own miner. So i went ahead and sent them 0.02176573btc. Approx $200 USD. After you send them btc i received the activation code via email. What you pay for actually is the code because the aoftware is free . and can be downloaded from the site. So i go thru the instructions , do as they say, and it only goes to 99 % complete …you need 100% to complete. Tried a hundred times ..never works …i email support 20 times ….finally i get a response ….telling me i needed admin copy , and a fresh browzer and turn antivirus off and all these things i dont have amd doesnt say anywhere on the site. They have a refund policy. Asked for my money back. They havent answered since.
