Cryptocurrencies work using a technology called blockchain. They are tokens that can be used as a form of payment in exchange for online goods and services. They carry a pre-determined store value of their own, just like any other fiat currency like the US dollar or the Indian rupee. Cryptocurrencies are digitally mined, where very sophisticated computers solve extremely complex computational mathematics problems. Their mining is painstaking, costly and only sporadically rewarding.
