That is what expected from a country like India where criminal cases are stretched so long that the victim gives up being tired and losing all his money in the case for the prolonged period of time.
Though RBI have a chance that the Supreme court will favour the RBI ban on cryptocurrencies, you never know what might happen and the unexpected might become the reality.
I wouldn't say that the current Supreme Court case against the RBI ban is being prolonged for a long time. Yes there have been cases which were dragged for a long time without judgement unnecessarily and leaving the criminals off the hook. But in this case, I haven't seen any such anomalies. No unnecessary adjournments were given, and the judges are hearing out both parties without a predetermined mind set. From the current situation, I would say that the judgement would most probably be favouring crypto.
Now that bigger companies like Facebook and Telegram are into cryptocurrencies I think that the chances of India regulating cryptocurrencies and bringing their own coin is damn very high.
Just because some major companies are launching their own cryptocurrencies, I don't think India will start their own cryptocurrency atleast not until some developed countries launch their own cryptocurrency.
