Government can just give Statutory warning, as they do in case of Mutul funds: "Mutual funds are subjected market risk", if we loose in MF, does the government provide any help... It does not matter whether Crypto-cuurencies are declared illegal tender, we should be allowed to invest on our own risk. Government of India does not provide any new job opportunities for the youth, the Jobless growth in India is dramatically increasing at exponential rate. If youth of India believe in this new "Blockchain" technology revolution, why the government also want to take this opportunity away.
