Bitcoin is a peer-to-peer payment system that uses the cryptocurrency of the same name. It works on its own blockchain, which keeps a record of all BTC transactions. The distributed network is supported by miners and full nodes.

Bitcoin was created in October 2008 by an anonymous figure (or perhaps collective) that goes by the pseudonym Satoshi Nakamoto, and it was launched in January 2009. In his honour, the smallest indivisible unit of Bitcoin (one hundred millionth) is called a satoshi. Bitcoin was the first decentralized digital currency and cryptocurrency. The currency’s issue is limited to 21 million coins, of which 18.8 million are already in circulation.

If you are looking for a cheaper place to buy bitcoin, our cryptocurrency platform will help you. It includes a simplified exchanger, so the transaction will not cause any difficulties. With its help, you can just as easily sell bitcoin at a competitive price. For professional traders, we have a full-fledged trading interface, and you can use it to profit from the bitcoin exchange rate with different strategies. In addition, BTC is already considered a reliable means of transfers and payments, so it can be used to pay for goods and services around the world.

Buy Bitcoin for USDT

All over the world, the US dollar is considered the main clearing currency, so it is easiest to monitor the exchange rates of other currencies against the dollar. And in the world of cryptocurrencies, it has been successfully superseded by USDT, Tether’s cryptographic analogue of the dollar. Based on the fact that 1 USDT is worth 1 USD, the BTC/USDT trading pair can be considered the prime tool for monitoring both the price of bitcoin online and the state of the cryptocurrency market.

Where to buy Bitcoin

1. Our cryptocurrency platform, which includes both an exchange and an online bitcoin exchanger, can be regarded as the most reliable place to buy bitcoin. We ensure the highest possible transaction speed, provide 24/7 support, and have secure wallets for storing BTC. In general, centralized platforms are still the safest place to trade bitcoin. Users trust officially registered companies with licensing, such as Polyx.
2. Decentralized BTC exchanges and p2p marketplaces are a slightly less secure alternative for conducting transactions with a cryptocurrency. At the same time, the majority of them can’t match the operation speed and liquidity of centralized platforms. However, this is one of the few ways to buy bitcoin anonymously.
3. Buying bitcoin in Europe is even possible through bitcoin ATMs (ATMs that sell and exchange BTC). They are becoming increasingly common, mainly in the capitals and large cities, but many have high transaction fees.
4. Message boards, forums, and social networks are the most obvious and familiar ways to make deals, but they are not safe. You will have to carefully check each seller so as not to encounter fraudsters. Similarly, it is best to take a relative with you to a face-to-face meeting as a precaution.

How to buy Bitcoin on the exchange

If you choose Polyx, you need to deposit a cryptocurrency. With USDT, ETH, LTC, or BCH on your balance, you can immediately start buying BTC. For those who want to buy bitcoin instantly, we suggest using the exchanger’s simple interface. This requires minimal effort: select the cryptocurrency to be given, enter the amount, select the cryptocurrency to be received (BTC), and click on ‘Exchange.’

For experienced users and professional traders, our advanced interface is the best way to buy bitcoins. All the functionality of the exchange will be available here: creating and executing orders, chart, and buying or selling bitcoin by limit. Moreover, each currency pair has its own trading page with DOM and history.

Where to store Bitcoin

Information about transactions (addresses and amounts) is available to all network participants in the Bitcoin blockchain. But, as the payment system does not require them, the identity of the sender and recipient are not displayed anywhere. Because of this, the cryptocurrency allows for pseudonymity, but not complete anonymity. One user can create any number of wallets in the form of addresses. Thus, keeping money in bitcoin is convenient and safe.

You can store BTC in the official Bitcoin Core client, but for that, you need to download the entire blockchain and run a full node. In October 2021, this required 367 GB, which is not very convenient, especially for mobile use.

For your convenience, we offer Polyx Crypto Wallet — a secure, fast, and mobile crypto wallet. It has a user-friendly interface and many useful functions for managing your crypto assets. Polyx Crypto Wallet is a non-custodial wallet that guarantees complete security of your cryptocurrency. Private keys are stored on your device only, so you will have full control.

Interesting facts about bitcoin transactions

• The BTC to USD exchange rate emerged in mid-2009, when people began to learn about cryptocurrency in narrow circles. The exact exchange value of bitcoin had not been determined, but exchangers had estimated 1200 BTC to be worth 1 USD.
• The first sale of bitcoins for US dollars took place in September 2009. It was Martti ‘Sirius’ Malmi who sent 5050 BTC to a user with the alias NewLibertyStandard. In return, he transferred 5.02 USD to a PayPal account.
• The first purchase of a real product with bitcoins took place in May 2010. It was Laszlo Hanyecz who paid 10,000 BTC for the delivery of two pizzas.

Later, the crypto community immortalised this event, deciding to commemorate Pizza Day on 22 May.
