Bitcoin is the world’s first cryptocurrency. With this means is that it is the “original” when it comes to digital and decentralized currency. That’s the biggest appeal of Bitcoin, it does not get printed by a central bank, and therefore in theory cannot expand beyond a preset limit, which is 21 million Bitcoins. Because of this, there are several advantages. The currency has a set limit as to how much can be produced. This keeps the idea of quantitative easing at bay, and allows for people to rely on a mathematical formula to understand that the market will not be flooded with Bitcoin. This system of payment is peer-to-peer, which means that end-users trade Bitcoin directly, without a bank for mediation. There is a public ledger called a blockchain that keeps a record of every transaction. Although it shows the amount of Bitcoin in every wallet, it does not identify those holders. This is what makes Bitcoin anonymous, which is a huge appeal to this currency.
