banning bitcoin , by saying that it can used for corruption and transferring black money, is just an excuse.
Indian Government, is doing everything to strengthen the banks and banking system.
A year ago Indian Prime Minister, did demonetization in India , by giving the reason that demonetization will eliminate corruption, but , it was just a silly excuse.
The reason for demonetization, was to strengthen the banks and the banking system.
Now Indian government is using the same old excuse of corruption. But the actual reason for banning bitcoin, is the banks.
Cryptocurrency is threat to banking system. Whereas Indian government has been trying to protect and strengthen the banking system, at any cost.

So naturally Indian government would be against bitcoin and any other Cryptocurrency.
