Unlike traditional currencies and assets, bitcoin is easily portable, divisible, and irreversible. Bitcoin is a new invention that is applicable to almost everything we do.
It can be viewed as a decentralized trust network that enables the verification of transactions without the need of a centralized third party.
If you take banking as an example, two parties can transfer currency or assets to one another without the need of a centralized entity like a bank to verify that the currency or assets have been successfully transferred.
Because the Bitcoin network is highly decentralized with no governing entity this makes the currency bitcoin a very attractive store of value when compared to fiat currencies that are not backed by any commodities and can be manipulated by monetary policies.
It will test really well. There is a wide variety of legislation in many different jurisdictions which could cause income, sales, payroll, capital gains, or some other form of tax liability to arise with Bitcoin.
Bitcoin is freeing people to transact on their own terms. Each user can send and receive payments in a similar way to cash but they can also take part in more complex contracts.
Multiple signatures allow a transaction to be accepted by the network only if a certain number of a defined group of persons agree to sign the transaction.
This allows innovative dispute mediation services to be developed in the future. Such services could allow a third party to approve or reject a transaction in case of disagreement between the other parties without having control on their money.
As opposed to cash and other payment methods, Bitcoin always leaves a public proof that a transaction did take place, which can potentially be used in a recourse against businesses with fraudulent practices.
It is also worth noting that while merchants usually depend on their public reputation to remain in business and pay their employees, they don't have access to the same level of information when dealing with new consumers.
The way Bitcoin works allows both individuals and businesses to be protected against fraudulent chargebacks while giving the choice to the consumer to ask for more protection when they are not willing to trust a particular merchant.
New bitcoins are generated by a competitive and decentralized process called "mining". This process involves that individuals are rewarded by the network for their services.
Bitcoin miners are processing transactions and securing the network using specialized hardware and are collecting new bitcoins in exchange.
The Bitcoin protocol is designed in such a way that new bitcoins are created at a fixed rate. This makes Bitcoin mining a very competitive business.
When more miners join the network, it becomes increasingly difficult to make a profit and miners must seek efficiency to cut their operating costs.
No central authority or developer has any power to control or manipulate the system to increase their profits. Every Bitcoin node in the world will reject anything that does not comply with the rules it expects the system to follow.
Bitcoins are created at a decreasing and predictable rate. The number of new bitcoins created each year is automatically halved over time until bitcoin issuance halts completely with a total of 21 million bitcoins in existence.
At this point, Bitcoin miners will probably be supported exclusively by numerous small transaction fees.
Bitcoins have value because they are useful as a form of money. Bitcoin has the characteristics of money durability, portability, fungibility, scarcity, divisibility, and recognizability based on the properties of mathematics rather than relying on physical properties like gold and silver or trust in central authorities like fiat currencies.
In short, Bitcoin is backed by mathematics. With these attributes, all that is required for a form of money to hold value is trust and adoption.
In the case of Bitcoin, this can be measured by its growing base of users, merchants, and startups. As with all currency, bitcoin's value comes only and directly from people willing to accept them as payment.
The price of a bitcoin is determined by supply and demand. When demand for bitcoins increases, the price increases, and when demand falls, the price falls.
There is only a limited number of bitcoins in circulation and new bitcoins are created at a predictable and decreasing rate, which means that demand must follow this level of inflation to keep the price stable.
Because Bitcoin is still a relatively small market compared to what it could be, it doesn't take significant amounts of money to move the market price up or down, and thus the price of a bitcoin is still very volatile.
Bitcoin price over time:. History is littered with currencies that failed and are no longer used, such as the German Mark during the Weimar Republic and, more recently, the Zimbabwean dollar.
Although previous currency failures were typically due to hyperinflation of a kind that Bitcoin makes impossible, there is always potential for technical failures, competing currencies, political issues and so on.
As a basic rule of thumb, no currency should be considered absolutely safe from failures or hard times.
Bitcoin has proven reliable for years since its inception and there is a lot of potential for Bitcoin to continue to grow.
However, no one is in a position to predict what the future will be for Bitcoin. A fast rise in price does not constitute a bubble.
An artificial over-valuation that will lead to a sudden downward correction constitutes a bubble. Choices based on individual human action by hundreds of thousands of market participants is the cause for bitcoin's price to fluctuate as the market seeks price discovery.
Reasons for changes in sentiment may include a loss of confidence in Bitcoin, a large difference between value and price not based on the fundamentals of the Bitcoin economy, increased press coverage stimulating speculative demand, fear of uncertainty, and old-fashioned irrational exuberance and greed.
A Ponzi scheme is a fraudulent investment operation that pays returns to its investors from their own money, or the money paid by subsequent investors, instead of from profit earned by the individuals running the business.
Ponzi schemes are designed to collapse at the expense of the last investors when there is not enough new participants.
Bitcoin is a free software project with no central authority. Consequently, no one is in a position to make fraudulent representations about investment returns.
Like other major currencies such as gold, United States dollar, euro, yen, etc. This leads to volatility where owners of bitcoins can unpredictably make or lose money.
Beyond speculation, Bitcoin is also a payment system with useful and competitive attributes that are being used by thousands of users and businesses.
Some early adopters have large numbers of bitcoins because they took risks and invested time and resources in an unproven technology that was hardly used by anyone and that was much harder to secure properly.
Many early adopters spent large numbers of bitcoins quite a few times before they became valuable or bought only small amounts and didn't make huge gains.
There is no guarantee that the price of a bitcoin will increase or drop. This is very similar to investing in an early startup that can either gain value through its usefulness and popularity, or just never break through.
Bitcoin is still in its infancy, and it has been designed with a very long-term view; it is hard to imagine how it could be less biased towards early adopters, and today's users may or may not be the early adopters of tomorrow.
Bitcoin is unique in that only 21 million bitcoins will ever be created. However, this will never be a limitation because transactions can be denominated in smaller sub-units of a bitcoin, such as bits - there are 1,, bits in 1 bitcoin.
Bitcoins can be divided up to 8 decimal places 0. The deflationary spiral theory says that if prices are expected to fall, people will move purchases into the future in order to benefit from the lower prices.
That fall in demand will in turn cause merchants to lower their prices to try and stimulate demand, making the problem worse and leading to an economic depression.
Although this theory is a popular way to justify inflation amongst central bankers, it does not appear to always hold true and is considered controversial amongst economists.
Consumer electronics is one example of a market where prices constantly fall but which is not in depression.
Similarly, the value of bitcoins has risen over time and yet the size of the Bitcoin economy has also grown dramatically along with it.
Because both the value of the currency and the size of its economy started at zero in , Bitcoin is a counterexample to the theory showing that it must sometimes be wrong.
Notwithstanding this, Bitcoin is not designed to be a deflationary currency. It is more accurate to say Bitcoin is intended to inflate in its early years, and become stable in its later years.
The only time the quantity of bitcoins in circulation will drop is if people carelessly lose their wallets by failing to make backups.
With a stable monetary base and a stable economy, the value of the currency should remain the same. This is a chicken and egg situation.
For bitcoin's price to stabilize, a large scale economy needs to develop with more businesses and users. For a large scale economy to develop, businesses and users will seek for price stability.
Fortunately, volatility does not affect the main benefits of Bitcoin as a payment system to transfer money from point A to point B. It is possible for businesses to convert bitcoin payments to their local currency instantly, allowing them to profit from the advantages of Bitcoin without being subjected to price fluctuations.
Since Bitcoin offers many useful and unique features and properties, many users choose to use Bitcoin. With such solutions and incentives, it is possible that Bitcoin will mature and develop to a degree where price volatility will become limited.
Only a fraction of bitcoins issued to date are found on the exchange markets for sale. Bitcoin markets are competitive, meaning the price of a bitcoin will rise or fall depending on supply and demand.
Additionally, new bitcoins will continue to be issued for decades to come. Therefore even the most determined buyer could not buy all the bitcoins in existence.
This situation isn't to suggest, however, that the markets aren't vulnerable to price manipulation; it still doesn't take significant amounts of money to move the market price up or down, and thus Bitcoin remains a volatile asset thus far.
That can happen. For now, Bitcoin remains by far the most popular decentralized virtual currency, but there can be no guarantee that it will retain that position.
There is already a set of alternative currencies inspired by Bitcoin. It is however probably correct to assume that significant improvements would be required for a new currency to overtake Bitcoin in terms of established market, even though this remains unpredictable.
Bitcoin could also conceivably adopt improvements of a competing currency so long as it doesn't change fundamental parts of the protocol.
Receiving notification of a payment is almost instant with Bitcoin. However, there is a delay before the network begins to confirm your transaction by including it in a block.
A confirmation means that there is a consensus on the network that the bitcoins you received haven't been sent to anyone else and are considered your property.
Once your transaction has been included in one block, it will continue to be buried under every block after it, which will exponentially consolidate this consensus and decrease the risk of a reversed transaction.
Each confirmation takes between a few seconds and 90 minutes, with 10 minutes being the average. If the transaction pays too low a fee or is otherwise atypical, getting the first confirmation can take much longer.
Every user is free to determine at what point they consider a transaction sufficiently confirmed, but 6 confirmations is often considered to be as safe as waiting 6 months on a credit card transaction.
Transactions can be processed without fees, but trying to send free transactions can require waiting days or weeks. Although fees may increase over time, normal fees currently only cost a tiny amount.
By default, all Bitcoin wallets listed on Bitcoin. Transaction fees are used as a protection against users sending transactions to overload the network and as a way to pay miners for their work helping to secure the network.
The precise manner in which fees work is still being developed and will change over time. Because the fee is not related to the amount of bitcoins being sent, it may seem extremely low or unfairly high.
Instead, the fee is relative to the number of bytes in the transaction, so using multisig or spending multiple previously-received amounts may cost more than simpler transactions.
If your activity follows the pattern of conventional transactions, you won't have to pay unusually high fees. This works fine.
The bitcoins will appear next time you start your wallet application. Bitcoins are not actually received by the software on your computer, they are appended to a public ledger that is shared between all the devices on the network.
If you are sent bitcoins when your wallet client program is not running and you later launch it, it will download blocks and catch up with any transactions it did not already know about, and the bitcoins will eventually appear as if they were just received in real time.
Your wallet is only needed when you wish to spend bitcoins. Long synchronization time is only required with full node clients like Bitcoin Core.
Technically speaking, synchronizing is the process of downloading and verifying all previous Bitcoin transactions on the network. For some Bitcoin clients to calculate the spendable balance of your Bitcoin wallet and make new transactions, it needs to be aware of all previous transactions.
This step can be resource intensive and requires sufficient bandwidth and storage to accommodate the full size of the block chain.
For Bitcoin to remain secure, enough people should keep using full node clients because they perform the task of validating and relaying transactions.
Mining is the process of spending computing power to process transactions, secure the network, and keep everyone in the system synchronized together.
It can be perceived like the Bitcoin data center except that it has been designed to be fully decentralized with miners operating in all countries and no individual having control over the network.
This process is referred to as "mining" as an analogy to gold mining because it is also a temporary mechanism used to issue new bitcoins.
Unlike gold mining, however, Bitcoin mining provides a reward in exchange for useful services required to operate a secure payment network.
Mining will still be required after the last bitcoin is issued. Anybody can become a Bitcoin miner by running software with specialized hardware.
Mining software listens for transactions broadcast through the peer-to-peer network and performs appropriate tasks to process and confirm these transactions.
Bitcoin miners perform this work because they can earn transaction fees paid by users for faster transaction processing, and newly created bitcoins issued into existence according to a fixed formula.
For new transactions to be confirmed, they need to be included in a block along with a mathematical proof of work. Such proofs are very hard to generate because there is no way to create them other than by trying billions of calculations per second.
This requires miners to perform these calculations before their blocks are accepted by the network and before they are rewarded.
As more people start to mine, the difficulty of finding valid blocks is automatically increased by the network to ensure that the average time to find a block remains equal to 10 minutes.
As a result, mining is a very competitive business where no individual miner can control what is included in the block chain. The proof of work is also designed to depend on the previous block to force a chronological order in the block chain.
This makes it exponentially difficult to reverse previous transactions because this requires the recalculation of the proofs of work of all the subsequent blocks.
When two blocks are found at the same time, miners work on the first block they receive and switch to the longest chain of blocks as soon as the next block is found.
This allows mining to secure and maintain a global consensus based on processing power. Bitcoin miners are neither able to cheat by increasing their own reward nor process fraudulent transactions that could corrupt the Bitcoin network because all Bitcoin nodes would reject any block that contains invalid data as per the rules of the Bitcoin protocol.
Consequently, the network remains secure even if not all Bitcoin miners can be trusted. Spending energy to secure and operate a payment system is hardly a waste.
Like any other payment service, the use of Bitcoin entails processing costs. Services necessary for the operation of currently widespread monetary systems, such as banks, credit cards, and armored vehicles, also use a lot of energy.
Although unlike Bitcoin, their total energy consumption is not transparent and cannot be as easily measured. Bitcoin mining has been designed to become more optimized over time with specialized hardware consuming less energy, and the operating costs of mining should continue to be proportional to demand.
When Bitcoin mining becomes too competitive and less profitable, some miners choose to stop their activities. Furthermore, all energy expended mining is eventually transformed into heat, and the most profitable miners will be those who have put this heat to good use.
An optimally efficient mining network is one that isn't actually consuming any extra energy. While this is an ideal, the economics of mining are such that miners individually strive toward it.
Mining creates the equivalent of a competitive lottery that makes it very difficult for anyone to consecutively add new blocks of transactions into the block chain.
This protects the neutrality of the network by preventing any individual from gaining the power to block certain transactions.
This also prevents any individual from replacing parts of the block chain to roll back their own spends, which could be used to defraud other users.
Mining makes it exponentially more difficult to reverse a past transaction by requiring the rewriting of all blocks following this transaction.
In the early days of Bitcoin, anyone could find a new block using their computer's CPU. As more and more people started mining, the difficulty of finding new blocks increased greatly to the point where the only cost-effective method of mining today is using specialized hardware.
You can visit BitcoinMining. The Bitcoin technology - the protocol and the cryptography - has a strong security track record, and the Bitcoin network is probably the biggest distributed computing project in the world.
Bitcoin's most common vulnerability is in user error. Bitcoin wallet files that store the necessary private keys can be accidentally deleted, lost or stolen.
This is pretty similar to physical cash stored in a digital form. Fortunately, users can employ sound security practices to protect their money or use service providers that offer good levels of security and insurance against theft or loss.
The rules of the protocol and the cryptography used for Bitcoin are still working years after its inception, which is a good indication that the concept is well designed.
However, security flaws have been found and fixed over time in various software implementations. Like any other form of software, the security of Bitcoin software depends on the speed with which problems are found and fixed.
The more such issues are discovered, the more Bitcoin is gaining maturity. There are often misconceptions about thefts and security breaches that happened on diverse exchanges and businesses.
Although these events are unfortunate, none of them involve Bitcoin itself being hacked, nor imply inherent flaws in Bitcoin; just like a bank robbery doesn't mean that the dollar is compromised.
However, it is accurate to say that a complete set of good practices and intuitive security solutions is needed to give users better protection of their money, and to reduce the general risk of theft and loss.
Over the course of the last few years, such security features have quickly developed, such as wallet encryption, offline wallets, hardware wallets, and multi-signature transactions.
It is not possible to change the Bitcoin protocol that easily. Any Bitcoin client that doesn't comply with the same rules cannot enforce their own rules on other users.
As per the current specification, double spending is not possible on the same block chain, and neither is spending bitcoins without a valid signature.
Therefore, it is not possible to generate uncontrolled amounts of bitcoins out of thin air, spend other users' funds, corrupt the network, or anything similar.
However, powerful miners could arbitrarily choose to block or reverse recent transactions. A majority of users can also put pressure for some changes to be adopted.
Because Bitcoin only works correctly with a complete consensus between all users, changing the protocol can be very difficult and requires an overwhelming majority of users to adopt the changes in such a way that remaining users have nearly no choice but to follow.
As a general rule, it is hard to imagine why any Bitcoin user would choose to adopt any change that could compromise their own money.
Yes, most systems relying on cryptography in general are, including traditional banking systems. However, quantum computers don't yet exist and probably won't for a while.
In the event that quantum computing could be an imminent threat to Bitcoin, the protocol could be upgraded to use post-quantum algorithms. Given the importance that this update would have, it can be safely expected that it would be highly reviewed by developers and adopted by all Bitcoin users.

Bitcoin-mining ASIC machines run very hot and consume large amounts of electricity. None of the developers expects to get rich because of it. Some use cases for individuals or groups such as merchants running a full node is for detecting double-spends or for increased privacy.
Bitcoin mining is analogous to the mining of gold, but its digital form. The process involves specialized computers solving algorithmic equations or hash functions.
These problems help miners to confirm blocks of transactions held within the network. Bitcoin mining provides a reward for miners by paying out in Bitcoin in turn the miners confirm transactions on the blockchain.
Miners introduce new Bitcoin into the network and also secure the system with transaction confirmation. They are also rewarded network fees for when they harvest new coin and a time when the last bitcoin is found mining will continue.
Bitcoins can be bought from various sources. You can purchase them online using an exchange or brokerage service that will enable you to buy Bitcoin with a bank transfer using fiat currency, a credit card, and some services also offer buying opportunities using Paypal.
Bitcoins can be sold in various ways. The currency can be sold online to an exchange or live in person locally. These same instances work similarly to the buying process.
You can sell your Bitcoin to the exchange at the current price it's being sold for. More anonymously you can sell in person or use Local Bitcoin.
Bitcoin payments are easy to make with a wallet application and addresses. You can use a standard desktop or smartphone to transact with an individual, merchant and exchange.
Addresses can be used in number form, in a QR code and contactless technology. Transacting with Bitcoin offers lower fees than any known remittance provider and credit card service.
No bank, no state, no third party can offer this low amount of fees. Bitcoin is a network operating by the three foundational principles of technological freedom: decentralization, open source code, and true peer-to-peer technology.
For every transaction, the sending and receiving addresses are publicly-viewable. This is also often used as an argument to attack Bitcoin as a currency for example like with illegal transactions.
If you publish your address anywhere, it can be linked to your real-life identity. Freely available blockchain explorers and analytical tools have been used to link addresses with only single transactions to other addresses, forming a chain or pattern that eventually reveals its owner.
These have been useful in investigating cases of theft at companies like Mt. Gox and Bitcoinica, but can potentially be used to identify anyone.
Think of it as a less memorable email address or online handle. There are ways to make Bitcoin more private, but they come with risks.
But do you trust the mixing service to spit your money out the other end, especially since most of them are run by anonymous entities themselves?
Another way is to trade Bitcoin for a digital currency designed to have greater anonymity , like Monero or DASH — effectively making your own mixer.
Trade Bitcoin for the other currency, perform one or more transactions to break the link, and trade back into Bitcoin. These transactions increase the complexity, though, and probably require an online exchange, which increases the potential to identify users.
Price volatility of all digital currencies may affect how much comes out the other end. And finally — like mixers — if the destination Bitcoin address is one that can be linked to you somehow, the entire process has been pointless.
The Bitcoin blockchain is public and permanent record. How likely is anyone to look? If private transactions are something you care strongly about your operational security should stay as ahead of the curve as possible.
The Bitcoin protocol can change the financial landscape we see today. The protocol can act as a currency, voting mechanism, global identification and reputation application, a micro-tipper, crowdfunding platform, initiate trusts, wills and contracts, decentralized domain names, future markets, and basically everything the financial system of today can handle plus so much more.
The currency application is just the beginning of this evolution of world's finances. Unfortunately, since unique private keys are associated with individual Bitcoin wallets, if the keys are lost, there is ultimately no way to retrieve that key without a passcode seed or other retrieval system; and that key is required to spend those coins.
However, most modern wallets have wallet and key backups that you can build prior to storing money. This will allow you to create a new private key so that you may restore your private key on a new wallet if lost.
Nobody is "in charge" of Bitcoin — at least in the sense that Bitcoin is not a company or organization, has no governing body and no organizational structure.
There are, however, certain groups who can exert influence over the way Bitcoin functions through various means. Again, though, there are no individuals who can claim to speak for these groups and they contain a plethora of opinions and incentives within.
Examples of such groups are:. Developers: These are the people who write and maintain the software the Bitcoin network runs on.
Although Satoshi Nakamoto released the first version of Bitcoin himself in , the code has since been re-written and updated by subsequent programmers.
The developers choose what updates to make to the protocol, and consider ways it can be improved. Miners: These are the people and companies that own the machines that generate new bitcoins and keep the network secure by validating transactions.
As a result, they have the power to "vote" with their hardware and choose which Bitcoin software to support. Developers may create and release radical revisions to the Bitcoin protocol, but they'll have no effect unless the Bitcoin miners choose to adopt them.
Users: That's you. At the end of the day, if regular users decide Bitcoin no longer fulfils their needs, then it will have no value. They have risen and fallen in favor as users decided whether to buy, hold, sell, or simply abandon.
Merchants have made individual decisions as to whether to accept them as payment or not. Bitcoin faces the same market conditions, and there's no shortage of new projects claiming their protocol is superior.
So far none have knocked Bitcoin from its position as the most popular cryptocurrency, but there's no guarantee this will always be the case.
Large holders, venture capitalists and influential figures in the "Bitcoin community" could also affect Bitcoin's future path, though their influence is less direct.
And again, there is rarely a consensus of vision among them. If you already know and want to see Bitcoin. Like the name suggests, a Bitcoin wallet is an application that stores, sends and receives bitcoins.
Other people have desktop versions or use browser-based wallets. Some apps have features that add value to your Bitcoin-using experience, like location-based Bitcoin business guides, links to exchanges to trade in and out of fiat currencies, more secure vault storage, or the ability to hold digital tokens other than just Bitcoin, such as any number of the many altcoins on offer.
Some wallets have central servers, meaning users have to create accounts with a login name usually an email address and password. These are less private and if login info and keys are not secured properly may be vulnerable to hackers.
If a user remembers the seed phrase, then the wallet can be restored elsewhere if the device is lost or broken.
These are the best options for users holding large amounts of Bitcoin. Bitcoin users now have a wide selection of wallets to choose from and features have improved vastly over the past couple of years.
But with more choice comes the need for more caution: fraudulent Bitcoin wallets have begun to appear that mimic the look of popular wallets, but are actually malware that steals bitcoins.
Until Bitcoin becomes the dominant currency for payments around the world, it will be more popular among traders and price speculators. As a result, the price is subject to the market forces of supply and demand which, at this point in time, goes hand in hand with the trends and whims of speculators — as a result, the price can move suddenly and sharply up or down in response to news events.
As a rule of thumb: if a piece of news makes Bitcoin more likely to be widely adopted, the price rises. If it places extra hurdles towards mass adoption, the price will fall.
You can track all the latest Bitcoin price movements in real time with Bitcoin. These events may be based on issues affecting the Bitcoin world only — such as a large scale hack affecting a key Bitcoin exchange, wallet or essential software which causes the price to dip.
This happened after the Mt. Gox meltdown in and thefts at Bitstamp and Bitfinex, plus numerous other smaller companies. News which affects the price may be only vaguely related to Bitcoin, or sometimes not at all.
The price sometimes fluctuates wildly for no apparent reason at all. The inverse happens if the price drops too far.
Some have suggested Bitcoin can never be adopted as a regular currency while prices are so volatile. In truth, if there was a sudden rush to Bitcoin among the general public maybe due to a crisis in a major fiat currency the price would probably rise dramatically and then stabilize — especially if there was nothing to swap it for, or no reason to do so.
In the meantime, if you think you can predict the big movements then good luck on the trading exchanges!
But be careful, it can also be inexplicable and unpredictable. There are plenty of reasons to want to trade Bitcoin for fiat and other digital tokens without an exchange.
The main one is security and trust — two of the largest Bitcoin exchanges of all time, Mt. Not to mention the multiple other smaller exchanges that were hacked or disappeared in mysterious circumstances.
Another is privacy — exchanges these days have similar know-your-customer KYC requirements to banks. Person-to-person trading is a small but growing market, with services like Local Bitcoin facilitating individual trade deals between users.
Some also use online classifieds like Craigslist or even chat groups on apps like Telegram and WeChat to indicate willingness to trade in person.
Other services like BitKan have special apps designed to introduce you to online buyers who may not be in your physical location.
As such, it is important to clarify your local laws before engaging in person to person trades. Yes… and no.
The days where anyone could make money mining Bitcoin with a desktop computer or GPU cards are unfortunately long gone. For a brief introduction to Bitcoin mining and some basic options, see Bitcoin.
After an hour or two, each transaction is locked in time by the massive amount of processing power that continues to extend the blockchain.
Using these techniques, Bitcoin provides a fast and extremely reliable payment network that anyone can use. Create a wiki account and get it activated.

Bitcoin is P2P electronic cash that is valuable over legacy systems because of the monetary autonomy it brings to its users.
Bitcoin seeks to address the root problem with conventional currency: all the trust that's required to make it work -- Not that justified trust is a bad thing, but trust makes systems brittle, opaque, and costly to operate.
Trust failures result in systemic collapses, trust curation creates inequality and monopoly lock-in, and naturally arising trust choke-points can be abused to deny access to due process.
Through the use of cryptographic proof, decentralized networks and open source software Bitcoin minimizes and replaces these trust costs.
Bitcoin Transactions are: Permissionless and borderless. The software can be installed by anybody worldwide. Do not require any ID to use.
Making it suitable for the unbanked, the privacy-conscious, computers or people in areas with underdeveloped financial infrastructure.
Are censorship-resistant. Nobody is able to block or freeze a transaction of any amount. Irreversible once settled, like cash. Transactions are broadcasted in seconds and can become irreversible within an hour.
Online and available 24 hours a day, days per year. Stored Bitcoins: Cannot be printed or debased. Only 21 million bitcoins will ever exist.
Have no storage costs. They take up no physical space regardless of amount. Are easy to protect and hide. Can be stored encrypted on a hard disk or paper backup.
Are in your direct possession with no counterparty risk. If you keep the private key of a bitcoin secret and the transaction has enough confirmations , then nobody can take them from you no matter for what reason, no matter how good the excuse, no matter what.Sie haben bereits eine Vorstellung davon, was der Bitcoin ist, aber noch offene Fragen?
