There is no official mechanism built into bitcoin to convert to another currency. Nothing inherently valuable underpins the bitcoin network. Bitcoin was created as a way for people to send money over the internet. The digital currency was intended to provide an alternative payment system that would operate free of central control but otherwise be used just like traditional currencies.
Cracking this is, for all intents and purposes, impossible as there are more possible private keys that would have to be tested 22 56 than there are atoms in the universe estimated to be somewhere between 10 78 to 10 There have been several high profile cases of bitcoin exchanges being hacked and funds being stolen, but these services invariably stored the digital currency on behalf of customers.
What was hacked in these cases was the website and not the bitcoin network. In theory if an attacker could control more than half of all the bitcoin nodes in existence then they could create a consensus that they owned all bitcoin, and embed that into the blockchain. But as the number of nodes grows this becomes less practical. A realistic problem is that bitcoin operates without any central authority.
Because of this, anyone making an error with a transaction on their wallet has no recourse. If you accidentally send bitcoins to the wrong person or lose your password there is nobody to turn to. Of course, the eventual arrival of practical quantum computing could break it all. Much cryptography relies on mathematical calculations that are extremely hard for current computers to do, but quantum computers work very differently and may be able to execute them in a fraction of a second.
Mining is the process that maintains the bitcoin network and also how new coins are brought into existence. The first miner to solve the next block broadcasts it to the network and if proven correct is added to the blockchain. That miner is then rewarded with an amount of newly created bitcoin. Inherent in the bitcoin software is a hard limit of 21 million coins. There will never be more than that in existence. The total number of coins will be in circulation by Roughly every four years the software makes it twice as hard to mine bitcoin by reducing the size of the rewards.
When bitcoin was first launched it was possible to almost instantaneously mine a coin using even a basic computer. Now it requires rooms full of powerful equipment, often high-end graphics cards that are adept at crunching through the calculations, which when combined with a volatile bitcoin price can sometimes make mining more expensive than it is worth.
Miners also choose which transactions to bundle into a block, so fees of a varying amount are added by the sender as an incentive. Once all coins have been mined, these fees will continue as an incentive for mining to continue. This is needed as it provides the infrastructure of the Bitcoin network. In the domain name. It set out the theory and design of a system for a digital currency free of control from any organisation or government.
It has implications for the velocity and use of currencies because it simplifies and streamlines transactions involving them. Bitcoin does not have the backing of government authorities, nor does it have a system of intermediary banks to propagate its use. A decentralized network consisting of independent nodes is responsible for approving consensus-based transactions in the Bitcoin network. There is no fiat authority in the form of a government or other monetary authority to act as a counterparty to risk and make lenders whole, so to speak, if a transaction goes awry.
The cryptocurrency does display some attributes of a fiat currency system, however. It is scarce, and cannot be counterfeited. The only way that one would be able to create a counterfeit bitcoin would be by executing what is known as a double-spend. This refers to a situation in which a user "spends" or transfers the same bitcoin in two or more separate settings, effectively creating a duplicate record.
What makes double-spending unlikely, though, is the size of the Bitcoin network. By controlling a majority of all network power, this group could dominate the remainder of the network to falsify records. However, such an attack on Bitcoin would require an overwhelming amount of effort, money, and computing power, thereby rendering the possibility extremely unlikely. But Bitcoin often fails the utility test because people rarely use it for retail transactions. The main source of value for Bitcoin is its scarcity.
The argument for Bitcoin's value is similar to that of gold—a commodity that shares characteristics with the cryptocurrency. The cryptocurrency is limited to a quantity of 21 million. Bitcoin is much more divisible than fiat currencies. One bitcoin can be divided into up to eight decimal places, with constituent units called satoshis. Most fiat currencies can only be divided into two decimal places for everyday use. If Bitcoin's price continues to rise over time, users with a tiny fraction of a bitcoin will still be able to make transactions with the cryptocurrency.
The development of side channels, such as the Lightning Network, may further boost the value of Bitcoin's economy. Bitcoin's value is a function of this scarcity. As the supply diminishes, demand for cryptocurrency has increased. Investors are clamoring for a slice of the ever-increasing profit pie that results from trading its limited supply. Bitcoin also has limited utility like gold, the applications for which are mainly industrial.
Bitcoin's underlying technology, called blockchain, is tested and used as a payment system. One of its most effective use cases is in remittances across borders to bump up speed and drive down costs. Some countries, like El Salvador, are betting that Bitcoin's technology will evolve sufficiently to become a medium for daily transactions. Another theory is that Bitcoin does have intrinsic value based on the marginal cost of producing one bitcoin.
Mining for bitcoins involves a great deal of electricity, and this imposes a real cost on miners. According to economic theory, in a competitive market among producers all making the same product, the selling price of that product will tend towards its marginal cost of production.
Empirical evidence has shown that the price of a bitcoin tends to follow the cost of production. Monetarists try to value bitcoin as they would money, using the supply of money, its velocity, and the value of goods produced in an economy. The simplest way to this approach would be to look at the current worldwide value of all mediums of exchange and of all stores of value comparable to Bitcoin and then calculate the value of Bitcoin's projected percentage. The predominant medium of exchange is government-backed money , and for our model, we will focus solely on that.
Roughly speaking, the money supply M1 in the U. El Salvador became the first country to make Bitcoin legal tender on September 7, The cryptocurrency can be used for any transaction where the business can accept it. One of the biggest issues is Bitcoin's status as a store of value.
Bitcoin's utility as a store of value depends on how well it works as a medium of exchange. If Bitcoin does not achieve success as a medium of exchange, it will not be useful as a store of value. Throughout much of its history, speculative interest has been the primary driver of Bitcoin's value. Bitcoin has exhibited the characteristics of a bubble with drastic price run-ups and a craze of media attention. This is likely to decline as Bitcoin continues to see greater mainstream adoption, but the future is uncertain.
Difficulties surrounding cryptocurrency storage and exchange spaces also challenge Bitcoin's utility and transferability. In recent years, hacks, thefts, and fraud have plagued digital currency. Like any asset or thing of value, the price that people are willing to pay for Bitcoins is a socially-agreed upon level that is also based on supply and demand. Because Bitcoins are virtual, only existing within computer networks, some people have a hard time grasping that Bitcoins are scarce and that they have a cost of production.
Because of this unwillingness to accept that digital traces can hold value in this way, they remain convinced that Bitcoins are worthless. Others who understand the Bitcoin system agree it is valuable. The market price of Bitcoin is highly volatile and subject to large price swings. As a result, the market price at any given time may vary wildly from its fair or intrinsic value.
Still, over time, oversold markets tend to rebound and overbought markets cool off. Thus, it is impossible to say at any given moment whether Bitcoins are fairly valued without the benefit of hindsight. While Bitcoin has several money-like features, economists and regulators remain unconvinced that Bitcoin currently acts as money.
This is because relatively few transactions are conducted in Bitcoins and very few things are denominated in Bitcoins. While people may trade Bitcoin in large volume and transfer value across the network, little commercial activity still takes place.
The cost to produce one bitcoin depends on the cost of electricity, the mining difficulty, the block reward, and the energy efficiency of miners. With a block reward of 6. Since each individual's situation is unique, a qualified professional should always be consulted before making any financial decisions.

When Nakamoto disappeared, hundreds of people posted theories about his identity and whereabouts. Some wanted to know if he could be trusted. Might he have created the currency in order to hoard coins and cash out? It appeared, though, that Nakamoto was motivated by politics, not crime. He had introduced the currency just a few months after the collapse of the global banking sector, and published a five-hundred-word essay about traditional fiat, or government-backed, currencies. Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve.
Banks, however, do much more than lend money to overzealous homebuyers. They also, for example, monitor payments so that no one can spend the same dollar twice. But with digital currency there is the danger that someone can spend the same money any number of times. Nakamoto solved this problem using innovative cryptography. Central banks and governments played no role. Bitcoin, however, was doomed if the code was unreliable. Earlier this year, Dan Kaminsky, a leading Internet-security researcher, investigated the currency and was sure he would find major weaknesses.
Kaminsky is famous among hackers for discovering, in , a fundamental flaw in the Internet which would have allowed a skilled coder to take over any Web site or even to shut down the Internet. Kaminsky alerted the Department of Homeland Security and executives at Microsoft and Cisco to the problem and worked with them to patch it. Bitcoin, he felt, was an easy target.
Only the most paranoid, painstaking coder in the world could avoid making mistakes. In a windowless room jammed with computers, Kaminsky paced around talking to himself, trying to build a mental picture of the bitcoin network. But when he found the right spot, there was a message waiting for him.
The same thing happened over and over, infuriating Kaminsky. He was like a burglar who was certain that he could break into a bank by digging a tunnel, drilling through a wall, or climbing down a vent, and on each attempt he discovered a freshly poured cement barrier with a sign telling him to go home.
Kaminsky ticked off the skills Nakamoto would need to pull it off. Soon after creating the currency, Nakamoto posted a nine-page technical paper describing how bitcoin would function. That document included three references to the work of Stuart Haber, a researcher at H. Labs, in Princeton.
Haber is a director of the International Association for Cryptologic Research and knew all about bitcoin. Haber noted that the community of cryptographers is very small: about three hundred people a year attend the most important conference, the annual gathering in Santa Barbara. In all likelihood, Nakamoto belonged to this insular world. If I wanted to find him, the Crypto conference would be the place to start.
It was a foggy Monday morning in mid-August, and dozens of college cheerleaders had gathered on the athletic fields of the University of California at Santa Barbara for a three-day training camp. Their hollering could be heard on the steps of a nearby lecture hall, where a group of bleary-eyed cryptographers, dressed in shorts and rumpled T-shirts, muttered about symmetric-key ciphers over steaming cups of coffee.
This was Crypto , and the list of attendees included representatives from the National Security Agency, the U. Cryptographers are little known outside this hermetic community, but our digital safety depends on them. They write the algorithms that conceal bank files, military plans, and your e-mail.
He is a friendly, diminutive man who is a professor of cryptography at the University of California at Davis and who has also taught at Chiang Mai University, in Thailand. He bowed when he shook my hand, and I explained that I was trying to learn more about what it would take to create bitcoin. Nakamoto had good reason to hide: people who experiment with currency tend to end up in trouble. In , a Hawaiian resident named Bernard von NotHaus began fabricating silver and gold coins that he dubbed Liberty Dollars.
Nine years later, the U. In , the federal government filed charges against e-Gold, a company that sold a digital currency redeemable for gold. The government argued that the project enabled money laundering and child pornography, since users did not have to provide thorough identification. The company was effectively shut down.
Nakamoto seemed to be doing the same things as these other currency developers who ran afoul of authorities. He was competing with the dollar and he insured the anonymity of users, which made bitcoin attractive for criminals. This winter, a Web site was launched called Silk Road, which allowed users to buy and sell heroin, LSD, and marijuana as long as they paid in bitcoin.
Still, Lewis Solomon, a professor emeritus at George Washington University Law School, who has written about alternative currencies, argues that creating bitcoin might be legal. Gray areas, however, are dangerous, which may be why Nakamoto constructed bitcoin in secret. It may also explain why he built the code with the same peer-to-peer technology that facilitates the exchange of pirated movies and music: users connect with each other instead of with a central server.
There is no company in control, no office to raid, and nobody to arrest. Today, bitcoins can be used online to purchase beef jerky and socks made from alpaca wool. In late August, I learned that bitcoins could also get me a room at a Howard Johnson hotel in Fullerton, California, ten minutes from Disneyland.
I booked a reservation for my four-year-old daughter and me and received an e-mail from the hotel requesting a payment of By this time, it would have been pointless for me to play the bitcoin lottery, which is set up so that the difficulty of winning increases the more people play it. When bitcoin launched, my laptop would have had a reasonable chance of winning from time to time. So I set up an account with Mt. Gox, the leading bitcoin exchange, and transferred a hundred and twenty dollars.
A few days later, I bought It was a simple transaction that masked a complex calculus. In , Richard Nixon announced that U. Ever since, the value of the dollar has been based on our faith in it. We trust that dollars will be valuable tomorrow, so we accept payment in dollars today. Once you believe in it, the actual cost of a bitcoin—five dollars or thirty?
Kim explained that he had started mining bitcoins two months earlier. He liked that the currency was governed by a set of logical rules, rather than the mysterious machinations of the Federal Reserve. A dollar today, he pointed out, buys you what a nickel bought a century ago, largely because so much money has been printed.
And, he asked, why trust a currency backed by a government that is fourteen trillion dollars in debt? He wanted bitcoin to succeed, and in order for that to happen businesses needed to start accepting it. Kim immediately exchanged the bitcoins I sent him for dollars to avoid just that risk. Still, the currency is young and has several attributes that appeal to merchants.
Robert Schwarz, the owner of a computer-repair business in Klamath Falls, Oregon, began selling computers for bitcoin to sidestep steep credit-card fees, which he estimates cost him three per cent on every transaction. Bitcoin does. At the Howard Johnson, Kim led us to the check-in counter. The lobby featured imitation-crystal chandeliers, ornately framed oil paintings of Venice, and, inexplicably, a pair of faux elephant tusks painted gold.
The receptionist handed me a room card, and Kim shook my hand. First of all, there is the flawless English. Over the course of two years, he dashed off about eighty thousand words—the approximate length of a novel—and made only a few typos. He covered topics ranging from the theories of the Austrian economist Ludwig von Mises to the history of commodity markets. This is a reference to a Times of London article that indicated that the British government had failed to stimulate the economy.
Nakamoto appeared to be saying that it was time to try something new. The text, hidden amid a jumble of code, was a sort of digital battle cry. It also indicated that Nakamoto read a British newspaper. In an initial post announcing bitcoin, he employed American-style spelling. But after that a British style appeared to flow naturally. A Frenchman onstage was talking about testing the security of encryption systems. The most effective method, he said, is to attack the system and see if it fails.
I ran my finger past dozens of names and addresses, circling residents of the United Kingdom and Ireland. An investment brokerage firm is a platform that allows investors to buy and sell stocks and cryptocurrencies. Companies like Robinhood allow retail investors to trade and invest commission-free, making them highly popular. Recently, payment services like CashApp , Venmo , and Paypal have introduced new features to their online platforms that allow users to buy, sell, and hold cryptocurrencies.
The platform also offers Bitcoin Boost, an opportunity to earn Bitcoin on purchases made with the CashApp card. Think cashback, except crypto. Currently, there are very few banks that allow the trade and storage of cryptocurrency, including online-only banks Ally and USAA. The examples outlined below are all examples of Bitcoin faucets, which are platforms that offer small amounts of Bitcoin in exchange for completing a task.
One of the most entertaining and fun ways to earn free Bitcoins is by playing mobile or online games. Some serve a lot of advertisements to their users. So, to avoid the ads, you can join a Bitcoin casino, where you bet your own money or Bitcoin on traditional casino games, sports matches, and lotteries to potentially win a higher payout in Bitcoin.
Another way to earn free Bitcoins is by completing tasks on websites. Some companies will pay you in Bitcoin to test their websites, take their surveys, retweet their posts, and complete other small tasks. There are also websites that let people offer small Bitcoin rewards to the person who can give them the best answer to one of their questions.
You can find odd jobs that pay you in Bitcoin on Cointiply. Certain cryptocurrency blogs, news outlets, and forums will pay you in Bitcoin to contribute your insights and write for them if you have a lot of knowledge about the industry. Popular cryptocurrency forums, like Publish0x , reward users for reading and writing articles relating to Bitcoin.
Image Source. On this site, users can earn Bitcoin along with other cryptocurrencies. They can also give tips to authors they enjoy. This answer to this question will vary greatly depending on your financial goals and your risk level. For instance, younger people tend to take on riskier investments as they have more time to wait out the market while older investors tend to be more conservative.
Cryptocurrencies are still considered volatile in the market, which has led financial advisors to call it a speculative asset — i.
