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.
Long before Bitcoin their were so many scam schemes and MLM is not new even in fiat currency their were so many MLM schemes runned and so many peoples have lost lot of fiat currency. so then it means then even fiat currency should be banned as it is also being used in illegal activities. It is nothing but government want to control the bitcoin and they are not able to do it that is why they just stated RBI to say banks to stop cryptocurrency trading accounts. But it is just like killing the democracy of the peoples right, which is not good. Very soon indian government will know this and they have to remove this ban and that time the boom in cryptocurrency will be sure.
