what is bitcoin and how do i buy it

Investing in cryptocurrencies and Initial Coin Offerings "ICOs" is highly risky and speculative, and this article is not a recommendation by Investopedia or the writer to invest in cryptocurrencies or ICOs. Since each individual's situation is unique, a qualified professional should always be consulted before making any financial decisions. Investopedia makes no representations or warranties as to the accuracy or timeliness of the information contained herein.

As of the date this article was written, the author owns no cryptocurrencies. On Feb. It may seem hard to believe that a digital currency could be worth thousands of dollars. After all, unlike physical currency, like precious metals or printed money, bitcoin is just lines of code.

So what makes bitcoin so valuable? The worth of currency used to be stipulated by precious metals. For the United States, that all changed at the height of the Great Depression when America faced mounting unemployment rates and spiraling deflation.

In , President Franklin D. Bitcoin functions by the same fiat principles as the U. Although the lines of code that make up each bitcoin are worthless in and of themselves, the international market has come to value each bitcoin at thousands of dollars.

When the bitcoin program was launched on Jan. According to the bitcoin program, however, the rate that bitcoin is produced cuts in half about every four years. On Nov. That rate halved again on July 9, , to At this rate, the total number of bitcoins in circulation will approach a limit of 21 million. Since the rate at which bitcoin can be produced cuts in half every four years, the currency becomes more difficult to obtain over time.

As of Feb. If the demand for bitcoin exceeds the rate at which it can be produced, the price will increase. That means investing in bitcoin now should be a sure-fire bet to pay off four years down the road, right?

Cryptocurrencies are wildly unpredictable, even ones as popular as bitcoin. At its most basic level, blockchain is literally a chain of blocks—only not in the traditional sense of those words. You have all these people, all over the world, who have bitcoin. According to a study by the Cambridge Centre for Alternative Finance, the number may be as many as 5.

This is where blockchain comes in. With blockchain, however, that job is left up to a network of computers. These networks often consist of thousands or in the case of bitcoin, about 5 million computers spread across the globe. When you go to make a purchase using bitcoin, that network of computers rushes to check that your transaction happened in the way you said it did. When consumers make purchases using the U. Solving a hash takes computers, and even supercomputers, an average of 10 minutes.

During that time, computers also check the accuracy of new transactions on the bitcoin blockchain. If a computer is the first to solve a hash, they store newly-made transactions as a block on the blockchain, at which point they become unalterable. When computers successfully add a block to the blockchain, they are rewarded with cryptocurrency. Earlier we discussed how the amount of bitcoin produced every 10 minutes cuts in half every four years. At the time of writing, computers receive In fact, the odds of solving one of these problems on the Bitcoin network are about one in seven trillion 12 zeros.

To put that number into perspective, the odds of winning the jackpot lottery are one in 13 million. To solve complex math problems at those odds, computers must run programs that cost them significant amounts of power, energy, and money.

Similar to winning the lottery, solving hashes essentially comes down to chance—but there are ways to increase your odds of winning in both contests. With bitcoin, arriving at the right answer before another miner has almost everything to do with how fast your computer can produce hashes. Just a decade ago, bitcoin mining could be performed competitively on normal desktop computers. Over time, however, miners realized that graphics cards commonly used for video games were more effective at mining than desktops and graphics processing units GPU came to dominate the game.

In , bitcoin miners began to use computers designed specifically for mining cryptocurrency as efficiently as possible, called Application-Specific Integrated Circuits ASIC. Today, bitcoin mining is so competitive that it can only be done profitably with the most up-to-date ASICs.

Even with the newest unit at your disposal, one computer is rarely enough to compete with what miners call "mining pools. A mining pool is a group of miners who combine their computing power and split the mined bitcoin between participants.

A disproportionately large number of blocks are mined by pools rather than by individual miners. In the real world, the power from the millions of computers mining on the bitcoin network is close to what Denmark consumes annually. Instead of leather, wallets are made up of two unique and distinct cryptographic keys: a public key and a private key.

The public key is the location where transactions are deposited to and withdrawn from. The private key is the password required to buy, sell, and trade the bitcoin in a wallet.

Personal Documents: The U. Securities and Exchange Commission requires users to verify their identities when registering for digital wallets as part of its Anti- Money Laundering Policy. Secure Internet Connection: If you choose to trade bitcoin online, use discretion about when and where you access your digital wallet.

Trading bitcoin on an insecure or public wifi network is not recommended and may make you more susceptible to attacks from hackers. Bitcoin wallets can connect directly to your bank account, debit card, or credit card.

Exchanges connect you directly to the bitcoin marketplace, where you can exchange traditional currencies for bitcoin. Anyone can view a history of transactions made on the blockchain, even you. But while transactions are publicly recorded on the blockchain, identifying user information is not. This is an important distinction. You may very well be ready to buy your first fraction of a bitcoin. Software wallets are mobile applications that connect with your traditional bank account. These wallets allow for quick and easy access to bitcoin, but the drawback is they put your money in the hands of a third-party company.

Although the leading software wallets are trustworthy, popular third-party companies have collapsed , or been hacked , in the past. For beginners, Coinbase is the best and easiest place to start because it is connected directly to a bitcoin exchange, which simplifies the buying and selling process. Hardware wallets are a little more old-school but tend to be considered more secure because they are kept offline.

In order to purchase bitcoin, you need to connect your wallet to a bank account, debit card , or credit card. Although these payment methods all perform the same function—exchanging traditional currency for bitcoin—they each carry their own set of fees. Transactions made using a bank account can take days to process on Coinbase, but are generally recommended for first-time investors.

By linking a bank account to your wallet, you can buy and sell bitcoin and deposit that money directly into your account. Bank accounts are generally recommended if you are dealing with larger sums of money. Debit and credit cards, on the other hand, allow you to buy bitcoin almost instantly.

The drawback is that on Coinbase and other popular exchanges, debit cards can only be used to purchase crypto—and even then, only in smaller amounts. Users cannot sell bitcoin or deposit money into their bank account when their wallet is connected to a debit card.

Just like when you go to make a purchase online, you have options. The same is true of buying bitcoin. Even if two exchanges trade the same cryptocurrency, it is likely that they each offer slightly different services.

Exchanges can vary in reputation, reliability, security, processing fees, exchange rates , and cryptocurrencies available for trading.

Before settling down with an exchange, date around. Here are our top five recommendations for where to start. Coinbase is the most popular and respected digital currency exchange in the United States. Although Coinbase only trades in five cryptocurrencies—Bitcoin, Bitcoin Cash, Ethereum, Litecoin, and Ethereum Classic—the exchange offers a way to securely buy and store cryptocurrency in one location.

Square is a huge financial technology company that includes many other services—one of which is trading bitcoin.

The Cash App allows users to buy and sell bitcoin without processing fees. Unlike most online exchanges, the Cash App stores your bitcoin in your Square Cash Account, rather than a separate digital wallet.

Robinhood launched in as a fee-free stock brokerage. In February , the company expanded into the bitcoin and ethereum markets, along with market data for another 15 currencies, allowing users to trade cryptocurrency without a fee. As is the case with Square, Robinhood stores bitcoin in the same Robinhood account that is used for stocks.

Robinhood is mobile-first and just recently added a web version, so it is best for people comfortable managing money from their phone or tablet.

The drawback of trading bitcoin on Robinhood is that the application is only available in 17 states, as of February If you feel comfortable trading on Coinbase and want to step up your trading volume, you may be ready to switch from Coinbase to Coinbase Pro.

Formerly known as Coinbase Global Digital Asset Exchange GDAX , the trading platform uses interfaces similar to Bloomberg terminals and active stock, commodity, and option trading platforms. Coinbase Pro offers options to make market orders, limit orders, and stop orders in addition to traditional buying and selling. Instead of trading exclusively from USD to cryptocurrency, Coinbase Pro allows users to trade between cryptocurrencies, say between ethereum and bitcoin.
