Archived from the original on 30 June It takes control back from central authorities. After an initial flurry of interest among merchants in accepting bitcoin in their retail or online stores, interest has largely died down as increasing bitcoin transaction fees and volatile price movements made it less attractive as a means of exchange. Cycling into Recession?
Why bitcoin?
Bitcoin is a peer-to-peer digital currency that can be safely and instantly sent to any person in the world. This currency is like electronic bitcoimwhich you can share with friends or use to pay for your purchases. Bitcoin is a currency unit of Bitcoin. Physical bitcoins also exist, but, generally, satndard is just a number connected to the address. Physical bitcoins are just objects like coins with inbuilt number. The main article: Satoshi Nakamoto.
Transactions
It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented in by an unknown person or group of people using the name Satoshi Nakamoto [15] and started in [16] when its source code was released as open-source software. They can be exchanged for other currencies, products, and services. Bitcoin has been criticized for its use in illegal transactions, its high electricity consumption, price volatility, and thefts from exchanges. Some economists, including several Nobel laureates , have characterized it as a speculative bubble. Bitcoin has also been used as an investment, although several regulatory agencies have issued investor alerts about bitcoin.
Bitcoin is a cryptocurrency created in 2009. Marketplaces called “bitcoin exchanges” allow people to buy or sell bitcoins using different currencies.

The main article: Satoshi Nakamoto. Satoshi Nakamoto is the name used by the unknown standad or persons who developed bitcoin, authored the bitcoin white paper, and created and deployed bitcoin’s original reference implementation. As part of the implementation, they also devised the first blockchain database. In the process they were the first to solve the double-spending problem for digital currency using a peer-to-peer network.
They were active in the development of bitcoin up until December Considering Bitcoin is a new technology, at first it can be unclear what it is and how it works.
People often see Bitcoin as one of three options:. If you spend much time online, you, probably, often meet an advertising of different scams.
These ads usually promise big benefit for simple work. Most often they convince people to buy certain block of shares that will bring ones ix of money. But in fact, customer has to spread more those ads without any gain. Bitcoin has nothing in common with such schemes. Bitcoin does not promise superior returns. Bitcoin is an experimental virtual currency, which is going to be a success or fail. None of the developers expects to get rich because of it. The majority of people using Bitcoin does not benefit from this, and client in the form it is distributed does not give you the opportunity to earn.
Few people with special highly productive equipment earn Bitcoins by » mining » creating new Bitcoinsusing special software, but Bitcoin should not be considered as a path to wealth. Most users participate in this project, because they consider its concept interesting, but they do not benefit from it. Bitcoin makes its first steps. Maybe great things await it in the future, but now it’s just a technology that can be offered to the people interested in conceptual projects or new technologies.
Bitcoin is a new, interesting e-Currency, and its value is not supported by governments or organizations. Like other currencies, it is worth something, because people are willing to exchange it for goods and services.
Its exchange rate is constantly fluctuating, sometimes very strong. Bitcoin lacks wide recognition; it is vulnerable to manipulation by persons without large assets. Security incidents, such as hacking a website and leakage of the accounts, can cause serious problems with uncontrolled selling of currency.
There are other probable fluctuations that can trigger feedback and cause much larger changes in the exchange rate. Anyone who invests in Bitcoinshould understand the risk he takes, and consider Bitcoin as a currency with a high level of baed. Later, when the Bitcoin becomes more famous and widely recognized, it may stabilize, but at this point everything is unpredictable.
Any investment in the Bitcoin must be exercised with a clear risk management plan. You can buy the physical bitcoins with PayPal, but it will be more difficult and expensive with electronic coins, because of the significant risk for the seller.
There is a method of buying Bitcoins via PayPal, but it is subject to a basde commission. Despite you may find someone who wants to sell you Bitcoins via Paypal, perhaps using bitcoin -otcmost exchanges does not work with PayPal. It is related to the high incidence of fraud: people paid for bitcoins via Paypal, received their bitcoins, and then sent a complaint to Paypal about not getting standqrd purchase at all. In this situation, PayPal often takes the side of the cheating buyer, so sellers have to insure against risks by higher commissions or complete rejection of Paypal.
Purchasing Bitcoins from individuals is still possible, but the seller must be sure the buyer will not complain to PayPal, to get his payment. New bitcoins are generated through the » Mining » process. During the process, which is similar to a permanent lottery, hosts are awarded with Bitcoins every time they find the solution to a mathematical problem and thus create a new block.
Creation of block is a work proof and complexity of the process varies with the growth of network. Award for the creation of the block is adjusted automatically. Thus every four years of the networking half of bitcoins is created, that have been created over the past four years. During the first 4 years January — November 10, Every four years, this amount will be divided in two; bitconi will be equal to 5, over the next four years, then 2,, and so on.
Thus, the total number of Bitcoins will never exceed 20, Blocks are mined every 10 minutes on average, and for the first four yearsblocks each block contained 50 new Bitcoins. Since the amount of processing equipment used in mining increases, the difficulty of creating new Bitcoins is growing.
This complexity factor is calculated every blocks; it bbitcoin based on the time it took to create the previous blocks. Their number is constantly increasing. How many parts bitcoins can be divided to? Bitcoin can be divided to 8 decimal places. It is also called «Satoshi» in honor of the founder of Bitcoin. If necessary, the protocol and software can be modified to work with smaller amounts. Supra are international SI prefixes for stnadard, thousandths and millionths parts.
The use of existing national symbols of money, whar as «cent», «nickel», «dime», «pence», «pound», «penny», is not supported, too, because it is a worldwide vitcoin. In the end reward for block declines from 0. Reward for the block is calculated as the bitwise shift of wjat integer to the right, so it is divided by two and rounded. If the original award was 50 BTC, then how many 4-year periods bitcoins have to be mined to reach zero?
How much time it takes to create all the coins? The last block generating coins will be the block numberwhich should be created in The total circulating number of coins will nased 20, Even if permitted accuracy increases what standard is bitcoin based on current 8 decimal places, the total circulating number of BTC will always be slightly below 21 million assuming that everything else will remain unchanged.
For example, with accuracy of 16 after the decimal point we finally would get 20, Even before the coins are over, commissions for the transactions included in the blocks will certainly become more rewarding for the creation of new blocks than the coins themselves.
When all coins are created, these commissions will support the use of Bitcoin and Bitcoin network. The number of blocks that can be created is unlimited. Because of a law of supply and demand bitcoins will cost more, provided their number reduces. So if some bitcoins are lost, others will grow in price to compensate. If the value of Bitcoins increases, number needed for purchase will decrease. This is deflationary economic model. Bitcoin protocol uses the basic block from one hundred million Bitcoins «Satoshi»but unused bits allow you to work with even smaller parts.
Bitcoin protocol allows using lightweight clients that can work without downloading on your computer the entire transaction history. As traffic grows and this point is becoming increasingly important, methods are developed to implement such concepts. Major network nodes will become more specialized services. With the help of some changes in the software full Bitcoin nodes will be able to catch up with VISA and MasterCard, but it will require a fairly humble hardware one high class server by today’s standards.
It is worth noting that the MasterCard network structure is similar to the Bitcoin — it is also a broadcast peer-to-peer network. Bitcoins are valuable because they are useful and their quantity is limited. The cost of bitcoins will be stable depending on that how many sellers will sell wares and services using bitcoins. Here you can find the list of sites, where you can pay by bitcoins. When we are talking that any currency is confirmed by the gold it means that theoretically you can trade this currency for gold.
Bitcoins as well as euro or dollars are confirmed by nothing except sellers, who accept it. Also bircoin spite of deficit is the most important demand for useful currency, deficit itself is not valuable.
In case there will be any confidence in bitcoins, so baed fact that the quantity of bitcoins will decrease, is not important. Demand will decrease and speculators in foreign currency will try to sell it stanxard soon as possible. Such a situation can be observed by example of state currencies in that cases when the state falls to several separate states and the currency of this state is not issued any more as the central body issuing new money disappeared.
In spite of limited quantity of money in circulation, its value decreases as the confidence wtandard its spending power is decreasing. Yes, it is, as euro and dollars are soup bubble and a fraud. But such possibility is hardly probable: even in Somalia where the state has fallen to pieces 20 years ago, Somali shillings are still accepted for payment.
In Ponzi scheme its founders persuade investors that they will grow rich. There is no central body, there only people who are building economy. Ponzi scheme is a play with zero amount of money. Those who have been involved to the scheme earlier will grow rich at the expense of those who were involved later. Bitcoin has win-win variants. Those who have been involved later and all society in general, will win due to stable, fast, cheap and widely-distributed p2p currency. The fact that people being involved earlier will get standxrd profits does not mean that bitcoin works according to Ponzi scheme.
All reliable investments have the same features.
