5th April 2018, RBI (Reserve Bank of India) announced that from now the bank's dealing with the cryptocurrency should disable their services to the exchanges.As soon as Russia adopted cryptocurrency USA adopted cryptocurrency they know the good cause and they believe in the technology.On the other hand these countries know the bad use of these technologies but they are taking serious measures on preventing the bad sides.Japan is the first country where cryptocurrency is made legal,they are very careful about these and they started making privacy coin banning like Zcash and Dash.But Japan didn't banned cryptocurrency instead they made ban on privacy coins.
India should rather take measures to avoid bad use and make strict regulations for the use of bad purpose.
Rather than running away India should adopt and work on the blockchain technology.India wants to be a super power in every terms than why India don't remove ban on cryptocurrency like Other super power countries.
Everything depends on the Supreme Court.The honourable Supreme Court should think about the future of India and make a fine decision for the citizens and for the India.
(These is my personal opinion)
Do comment on what RBI should do.
