If the government was really worried about Bitcoin, they could impose an outright ban.
Even if they impose a ban people would still trade and the only thing they wanted is to shut down the exchanges and they are doing it by stopping the flow of money and i am not sure what to take from this situation as all the exchanges will be trading only in crypto and not with INR making it impossible to deposit or withdraw which pretty much sucks to the core.
The Prime Minister seems to be pretty pro-blockchain and pro-cryptocurrency. Would that have any bearing on Misraji? What other political angles can come into this? There is the "terrorist, money-laundering, black money, 15 lacs" issues.
These are the things they can showcase but if they can regulate the entire market then they can make it impossible to make these illegal transactions, even without regulations the exchanges are pretty strict with their KYC policies and this will eliminate bad players as all the transactions are open and it can be linked.
