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.
