One of my friend also assemble rig. I purchased 2 rigs each with 170 MH/S mining two coins together. She made atleast 50 rigs. Very enthusiast about cryptocurrency . she is also an IITian. Only bad point she took all money in advance thats also inform of bitcoin but no loss I got my rigs in 7 days of payment.You can contact at

From all my 5 years of past experience, this pretty much seems a scam.
Here he claims a friend gave him a rig. And now she's his wife.
Pretty sure "Vanisha Soni" does not exist.
Then to make people trust he claims he paid first and then got delivery.
Also adds the standard "IIT" badge to make it seem more trustworthy.
