The matter is very subjective and need investigation. Raj kundra may also be a victim of that scam like many other ppl who joined it and then promoted it to there social media/friends to get more commission as referral, a typical formula of MLM scheme.
I remember in March 2017 there was a ASSOCHAM’s “Global Summit” On Bitcoin And Blockchain Technology where Mr. PP Chaudhary, the union minister of state for law and justice and electronics and information technology were also present.
It was a stage from where ppl came to know about Amit bharadwaj, No body actully know, who is going to become a scammer.
Shilpa shetty and few other celeb were also tweeted to promote this scam that time.
