What are Bitcoins?
Bitcoin(s) is an innovative payment system invented by Satoshi Nakamoto in the form of digital currency that is created and held electronically. It uses peer-to-peer technology to operate with no central authority or banks. Bitcoin is open-source, and nobody owns or controls it.
Unlike dollars, euros, and other currencies, bitcoins are not printed. You can buy bitcoins from either exchange or directly from other people via marketplaces. You can pay for them in a variety of ways, ranging from hard cash to credit or debit cards to wire transfers, or even with other cryptocurrencies, depending on who you are buying from and where you live. Ownership of bitcoins implies that a user can spend bitcoins associated with a specific address.
