Bitcoin (bitcoin is also used) is the unit of account of a peer-to-peer payment system. The difference between the system is the execution of an electronic payment between two participants without the presence of a third (bank, government agencies), in which no one can intervene, forcibly make, challenge or cancel the transaction. The popularity of bitcoin has led to the fact that it is successfully bought and sold through online services. They are called exchanges, although technically they are not, they do not have exchange licenses, and sometimes they are trivially hacked. Be careful: due to the unregulated nature of bitcoin, some of the services that call themselves exchanges actually turn out to be fraudulent websites and services.

Bitcoin exchange
How the bitcoin exchange works is easy to understand. To begin with, you should know that the exchange is in fact a banal service for exchanging from digital currency (bitcoin) to other types of assets, and first of all, national currencies. Operations are sometimes carried out with insufficient technical protection, and the legal side of the case does not allow protecting "traders" from hacking and theft of cryptocurrencies. The most famous sites are Mt.Gox, Cryptsy, BTC-E, Bitfinex, Chinese OKCoin, Huobi, BTC China (on each of them, from 100 to 200 thousand bitcoins are exchanged per day - according to data for 2015). The so-called margin trading, which is characteristic of ordinary stock exchanges, is also possible on the sites.

Bitcoin exchange: how to make money
The main way to make money on bitcoin exchanges is to use the exchange rate difference. By the way, it can be from several tens of percent (during the day), and in large periods the cost can change by several tens of percent. However, many experts consider Bitcoin to be a speculative instrument, the rate of which and purchasing power change depending on rumors and growth in demand. The real cost of bitcoin is extremely difficult to estimate.

In addition, earnings are possible in other services that offer captcha input from an image or visiting sites and viewing ads for a small amount of bitcoins. Then these funds can be used to trade bitcoins or to withdraw to any national or cryptocurrency on the exchange.

Bitcoin exchange rate
The cryptocurrency rate on bitcoin exchanges changes every day. The market price (rate) of bitcoin in October-November 2014 reached $ 412, the minimum rate of about $ 180 was recorded in mid-January 2015, and in September 2015 the rate was in the corridor of $ 225-240 per bitcoin ...

In addition to the course itself, which is displayed in the form of a graph and in a tabular form, many services, also before using cryptocurrency and playing on stock exchanges, it is worth clarifying:

the amount of bitcoins in circulation,
the dynamics of the amount of mined bitcoins,
number of transactions per day,
volume of transactions in USD on leading exchanges,
the ratio of the current trading volume to the volume of all transactions (in BTC to USD),
the computing power of the Bitcoin network (hash rate) in gighashes per second.
Interesting fact. In 2013, the bitcoin rate increased by 5580%.

Trading bitcoins on the exchange
The strategies are all the same as on conventional stock exchanges and binary options.

For trading, you can use exchanges with both fiat currencies (real, backed by national currencies) and non-fiat ones. The first are:

Mt.Gox,
Cryptsy,
BTC-E,
OKCoin,
Huobi,
BTC China.
The main interface elements when trading bitcoins on the exchange are

graphs,
buy and sell orders (Buy / Sell orders),
history of transactions,
trading volume.
The most noticeable difference between such exchanges in comparison, for example, with stock exchanges, is significant fluctuations in the exchange rate, which means a smaller amount of funds required to obtain tangible profits.

What is a bitcoin exchange and how to register in it?
By itself, the concept of "bitcoin" denotes the concept of "digital currency" in the modern foreign exchange market. It differs from ordinary money only in that it is impossible to "hold it in your hands." And where there are currencies, of course, there will be bitcoin exchanges. Exchanges of this kind are created specifically in order to trade cryptocurrencies, to make money on the difference in currencies. The turnover of your income will largely depend not only on the rate, but also on the trading volume.

The bitcoin quote is not formed by itself - it is based on the presence of demand for a particular currency and the number of offers for its sale on the market. Bitcoins are not tied to assets in any way. And if the liquidity of an ordinary currency is tied to a centralized authority, then this does not happen with a cryptocurrency.

The value of bitcoins on the exchange largely depends on what goods or services can be paid on the market with their help. This is where the demand for a particular cryptocurrency is born. Registration on the bitcoin exchange is not difficult for the average trader.

How does the buying and selling process work?
There is nothing complicated here. In order to start trading, a person needs to replenish his own account in the "Deposit" section on the exchange using any of the proposed methods (banks, e-wallets, etc.). You can buy bitcoins in the "Buy / Sell" section. If you choose "InstantOrder", it is enough to make a quick purchase of cryptocurrency, indicating how much you plan to do it. The exchange system will independently find bitcoins at the cheapest price and complete the transaction. If you choose "LimitOrder", you will need to choose the bitcoins to buy on your own, analyzing the existing offers. Selling works in a similar way.

What to look for when choosing exchanges?
There are several factors to consider when choosing an exchange:

Exchange commission. This is important because your earnings will ultimately depend on the size of the commission. On most trading platforms, the rule is: the commission percentage is lower the more purchases you make.
The legality of the site. In some countries, there is still no official permission to use cryptocurrencies. In some, its use is associated with certain rules and regulations. Always consider where the marketplace you plan to use is located.
Check how this or that bitcoin exchange cares about the safety of its customers. Otherwise, you risk losing all your money in one moment.
At the site of your choice, the jump in the value of the cryptocurrency should be within the normal range. If the indicators are too high, such a trading platform cannot be called reliable.
