cryptocurenccy as a decentralized currency. If the government adopts cryptocurenccy, then I think it will eliminate the cryptorurenccy concept. Because the government will implement regulatory regulations such as fiat money.
Remember that not all cryptocoins are decentralized, some of them are actually regulated or controlled by someone, so I think India would make its own cryptocurrency regulated, however there are lots of pros and cons with a regulated crypto, lets just hope that India will do well.
