So what exactly is Bitcoin? Bitcoin is a digital currency and digital payment system that allows people to send and receive Bitcoins â or digital tokens â to anyone, anywhere in the world. It runs on a decentralized network of computers in which all transactions are recorded, verified and updated by technology known as blockchain, which is akin to an online public ledger.
Bitcoin is an anonymous digital currency... Bitcoin is not real money. It's an online currencyâvirtual tokens that can be exchanged for goods and services at places that accept it, the same way you'd give someone a dollar for a cookie.ust like you can trade in yen for dollars, you can swap your BitCoins with other users for several real world currencies. And right now, the BitCoin is trading very high! When we first published this post in May 2011, one Bitcoin was worth $7.50. Today it's over $250. And climbing. And climbing and climbing.
