2017 was a great year for crypto in India while few scammers also scammed many of ppl like amit  bharadwaj's gainbitcoin. There are still many MLM schemes are growing in India recently I have heared about 3xBit.
These scam gives change to the government to ban crypto as ppl are getting scammed through it. For 2017 This gainbitcoin is like a black spot for crypto users.
Govt is already in negative mood with this all crypto stuff so you can not predict anything about future in 2018. If there is any positive news from govt side crypto will surely boom in India else there is no future.
