What is Cryptocurrency?

Cryptocurrency (crypto coin) is a form of digital or virtual currency that uses cryptography for security. It operates on decentralized networks based on blockchain technology, which ensures transparency, security, and immutability of transactions. Cryptocurrencies are independent of centralized authorities like banks or governments.

India has not classified cryptocurrencies as illegal, but they are not recognised as legal tender. Sahil Arora, partner at Saraf and Partners, described their position as “legally nuanced.” source
