Until relatively recently, the world did not even know that a new financial asset had appeared. It was cryptocurrency, bitcoin. Blockchain technology and cryptocurrency powered by this latest technology are considered by many to be almost a cosmic gift. 

Whether cryptocurrency is a cosmic gift, or is it a product of the intelligence of an earthling, but cryptocurrency is one of the most profitable financial assets. 

Cryptocurrency can be mined on your own right at home, if you have the appropriate equipment. Or by connecting to cloud servers. Another way to become the owner of a technological financial asset is to buy cryptocurrency on an exchange. 

How can you buy cryptocurrency on an exchange and which cryptocurrency exchanges are the most reliable?

How to choose the best exchange for a beginner crypto investor
When choosing a cryptocurrency exchange, a novice investor needs to focus on some indicators. Such as

What is the financial turnover of the crypto site? Large financial turnovers indicate that there is a sufficient amount of money in the bins of the exchange. This platform is used by a large number of traders. This means that such an exchange is of high quality and the trader will not have any problems with it.  
Pay attention to the reputation of the crypto exchange. All the information you need is available on the Web. These are reviews, comments, media data.
The amount of commission fees, which is not the same everywhere. A beginner without large capital should choose lower commissions. 
For residents of different countries, crypto exchanges can set geographic limits. For example, citizens of the United States do not have access to many commercial sites.
Pay attention to the number of pairs traded on the cryptocurrency platform and their market rate. It is advisable to select a site where there is a large selection of cryptoassets. Cryptocurrency exchanges offer their own currency conversion rates. 
You should study payment options, find out how and how quickly you can transfer money to the account of the crypto exchange, and then withdraw it to your account or card.
The largest cryptocurrency exchanges in terms of money volume:
Binance, whose cash turnover exceeds $ 2.5 billion per day.
Bubit, with a turnover of over $ 1.5 billion.
Huobi, the daily turnover of the site is more than $ 1 million.
StormGain, the daily financial turnover of the site is approaching $ 1 million.
Exmo, the daily turnover of the crypto exchange is also almost $ 1 million.
What are cryptocurrency exchanges?
All cryptocurrency exchanges are subdivided into:

Centralized cryptocurrency exchanges,
Decentralized cryptocurrency platforms,
Crypto exchangers with cryptocurrency storage,
Cryptocurrency exchangers without cryptocurrency storages.
Centralized cryptocurrency exchanges
The first category, that is, centralized cryptocurrency exchanges, includes online platforms where you can trade cryptocurrency and ordinary fiat money at the same time. 

A centralized cryptocurrency exchange operates on the principle of a public or private bank. A client who wants to make any transaction, for example, buy ether or bitcoin, entrusts his finances to the chosen cryptocurrency platform. 

Centralized cryptocurrency exchanges are briefly denoted by CEX symbols. 

Before starting to work with a centralized cryptocurrency exchange, each potential user must go through a mandatory registration procedure and then a complex verification procedure.  

Each client has a special digital key-password for his section of the cryptocurrency storage. Even in case of loss of the electronic key-password, its data can be restored thanks to a special intermediary of the crypto exchange, which will help to recover the lost key.   

Status centralized cryptocurrency exchanges are as safe as the banks we are used to. But even in relation to such sites, many fraudulent attacks have been recorded, the purpose of which is to steal cryptocurrency. 

Cryptocurrency centralized exchanges
Coinbase, one of the world's most popular cryptocurrency centralized platforms. Coinbase supports transactions with bitcoin, bitcoin cash, ether, litecoin.
Gemini, based in New York, is regulated under the jurisdiction of the United States. Supports work with ether and bitcoin.
Kraken makes transactions with dollars, euros and various crypto assets.
Decentralized Cryptocurrency Exchanges (DEX)
Decentralized cryptocurrency exchanges work in a different way. Decentralized crypto exchanges do not have one or a group of executives. 

The fact that no one controls the exchange is just evidence that the work of the exchange is not subject to any orders from the center. This is a decentralized platform.

All blockchain nodes that form the exchange network operate on the principle of a smart contract. The process of buying and selling or exchanging cryptocurrency here takes place without control from the main server.

Each of the DEXs can differ in blockchain architecture or can be tied to work with some specific or with different cryptocurrencies. 

On decentralized cryptocurrency exchanges, you can also buy, sell or exchange not only tokens of different architecture, such as bitcoin or more complex ether, but also make transactions with fiat money.

To use the service of decentralized cryptocurrency exchanges, you need to register on the exchange and then go through the identity verification procedure. 

If we evaluate cryptocurrency exchanges by the level of security, then the crypto assets of DEX clients are more secure than the financial assets of users of centralized crypto exchanges. 

The main reason for DEX security is the decentralized blockchain architecture. However, a client of a decentralized cryptocurrency platform must also go through a complex authentication procedure. 

This is done in the interests of the client himself in order to create a more complex mechanism for protecting the user's financial assets and protect them from all kinds of fraudulent encroachments.

Most popular DEX:
WavesDex,
Bancor,
Bitter,
Uniswap.
Crypto exchangers with cryptocurrency storages
Crypto exchangers are not intermediaries between the buyer and the seller. These cryptocurrency platforms trade directly with clients. Crypto exchangers charge a commission for their work.

Commission rates may differ in value on different crypto platforms. Therefore, of course, it is worth choosing cryptocurrency platforms with more favorable commission fees.  

Before starting work with the exchange, the client, as in the case of a centralized crypto exchange, must transfer money to the account of the crypto exchanger. On the platform of such a crypto exchanger, it is possible to store tokens, buy and sell.

Crypto exchanges with a storage function often offer customers to register on the exchange and then be verified. of course, it is better to go through this procedure, since after passing it, each client of the exchanger has the opportunity to make large financial transactions.

Without registration, there is a certain limit on the volume of financial transactions. Only a small number of tokens can be bought or sold. For a beginner crypto investor, this is a perfectly suitable offer. 

Each cryptocurrency platform introduces its own limit on exchange or buying and selling without registering on a crypto platform. But these conditions can change.    

The most popular crypto exchangers with storage:  
Binance 
Bitmex  
Coinbase
bitpanda
Coinmama
Crypto exchangers without cryptocurrency storage
Crypto exchangers without a crypto asset storage service, after the end of a monetary transaction, transfers funds to the client's account or to a bank card. 

This is perhaps the fastest way to purchase cryptocurrency without going through the registration and verification procedure.  

It is only necessary to have one condition for the client - to have their own crypto wallet. 

The downside of such crypto platforms is that the commissions are quite high here. And the exchange price can not always be called fair. 

Crypto exchangers without a cryptocurrency storage function may offer the client to register officially as well if money transactions are too high in volume. There have been cases when such crypto exchangers blocked the client's funds, considering them "dirty".
