Satoshi Nakamoto developed the first decentralized cryptocurrency called Bitcoin (BTC) and referred to it as “a peer-to-peer electronic cash system.” As per Bitcoin’s white paper, online payments could be made directly from one party to another without going through a banking institution with a peer-to-peer version of electronic cash.
That said, other than using Bitcoin as an investment vehicle or a store of value, it can be used to pay for goods and services. Similarly, other cryptocurrencies like Dogecoin (DOGE) can be used to pay bills online with crypto.
