Quite bad news for Indian crypto adoptors as India has a huge population they could have used cryptocurrency for developing their economy. So far I know they might change their decision. Crypto user can use an alternative way for the transaction. So it is really pathetic and impatient incident for Indian huge crypto lovers.
The policy of banning the use of cryptocurrency in India is theoretically possible, but in practice it is very difficult to prohibit, because all transactions occur on the internet, so no one knows because it can use a server from a country where cryptocurrency is legalized.
