Packed with plenty of screenshots, Learning Bitcoin is a simple and painless guide to working with Bitcoin. I think the fact that within the bitcoin universe an algorithm replaces the functions of the government …[that] is actually pretty cool. Bitcoin's potential is quickly becoming apparent in the rapidly changing world of Internet finance.
In just the few short years since its launch, we have seen an explosion of interest in this new, and somewhat mysterious, Internet money. Yet, several questions quickly come to mind: How does it work? Where does it come from? How do I buy it? In this chapter, we will illustrate, in simple terms, most of what anyone new to Bitcoin will need to know to start.
We will start by covering the following core topics:. Humans have been trading various forms of money for thousands of years. Many types of precious objects, acting as a Medium of Exchange , have been used. In the early ages, we traded grain, cattle, shells, and gems for other goods and services. This type of money, which we can touch and see, can be considered Physical Money.
As civilization progressed, so did our political systems. Eventually, sparse tribes and villages consolidated into kingdoms, states, and empires. Through the transformation, we saw our money shift into Political Money ; money that's governed and issued by a central body such as the King, Emperor or, as in today's society, a Central Bank.
State issued coins, bills, and notes, as well as taxation, regulation, and monetary policy—all emerged from this shift. Today, Internet technology connects us directly to each other, opening a vast range of possibilities. By dissolving pre-existing physical and political boundaries, for the first time in history, the entire planet has access to the same information.
This level of access is guaranteed by the Internet's decentralized design. Without a centralized hub, there is no single point of failure or control. Satoshi Nakamoto, the creator of Bitcoin, leveraged this powerful network to implement a peer-to-peer P2P system for exchanging virtual cash. Built on a decentralized design and protected by powerful cryptography, this new type of money is no longer physical, yet resilient against corruption and manipulation.
No single group of individuals, including governments, banks, and corporations, control Bitcoin because all the peers are equal actors, participating through the same protocol. Its monetary policy is defined and self-regulated by its open network of computers. Thus, with Bitcoin we're seeing the emergence of a new phase of money. This P2P money is called cryptographic money or simply Crypto-Currency. Buying bitcoin is similar to buying foreign currencies. Just as there are many exchanges for exchanging government currencies, there are many exchanges for exchanging bitcoins.
Today there are markets for exchanging bitcoin with most of the world's major currencies. Most of them are online markets through which you can connect your bank account or credit card. There are some markets where the buyer and seller meet in person to exchange by hand.
For the more technical users, private markets exist on chat forums where anonymous users trade with the other users based on their online reputation. Of all the diverse ways to buy bitcoin, using a reputable online exchange may be the likely option for most users. Online exchanges generally operate similar to conventional online banking systems and are easy to set up. We're going to buy 25 dollars worth of bitcoin using a credit card with an online exchange called Circle.
In , Circle was launched by a team competent in technology and finance. Additionally, they are registered as a money transmitter with FinCEN, a US government agency responsible for safeguarding the financial system from illicit use. For US citizens, they offer an instant exchange with a user-friendly wallet service.
To buy bitcoins with Circle, you'll need the following:. Buying and selling bitcoin on Circle is only available to users with a US address. These are the requirements to accept bank transfers from the US banking system. What's important to remember about Bitcoin is that the currency exists independently of any government's requirement for an individual's identity. Bitcoins can be exchanged with cash, hand-to-hand, thus by passing the registration process that we will describe in this chapter.
While it is generally safe to do so, some users may be at risk from local regulations. It is important to research the local currency laws before transacting through these services, especially with large amount of cash.

Finally, Circle will prompt you to provide two security questions. In case you lose your password, these questions will be asked before you can reset it.
