What’s a Bitcoin? Basic information

Bitcoin (abbr. BTC) is the oldest cryptocurrency in the world. It was created in 2008 by a person or a group of people, hiding under the codename Satoshi Nakamoto. The coin differs from other currencies you know so far, such as Polish Zloty or American Dollar - it does not exist in a physical form.

Bitcoin, as all the other cryptocurrencies, is placed on a so called blockchain. In other words, it is located in a decentralized, scattered net. It means that it cannot be managed by a single unit or institution. The control over this virtual coin is spread owned all the users of the net.

Now you know what a Bitcoin is, or at least have a general idea of it.  But I bet you wonder - why was it created? Why would anyone need a virtual currency, that does not exist in a physical form and, in addition, is placed on an unfamiliar formation called the blockchain.

Well, according to the creator of Bitcoin himself – Satoshi Nakamoto, cryptocurrency was supposed to be an alternative to fiat money. As you probably know, traditional currency is influenced by inflation (is loses value over time) for example due to incompetent government of a given country.

In case of Bitcoin it’s totally different. First of all, its supply has been decided in advance, which means there cannot be more that the 21 million coins. Second of all, because it is placed on a blockchain none of the national institutions or bank can take control over it. Destruction or elimination of Bitcoin is virtually impossible, because it is spread over thousands of servers around the world.

Although Satoshi Nakamoto himself wanted Bitcoin to be used for immediate transactions, with no constraints regarding time or country, today this cryptocurrency can be used in three different ways. For some people it is just a virtual money, that can be easily and quickly transferred from one end of the world to the other, at any time of day or night. Others see Bitcoin as a speculative asset, which can bring a big return on investment. There are also those who treat the cryptocurrency as a safe way to store their savings. 

Bitcoin basic functions


Used to deal. Single transaction takes 8 minutes on average. There are no time constraints. To transfer BTC to someone else you do not need to use any bank or other financial institution services. The quantity of BTC you own is assigned to the public address of your cryptocurrency wallet, in this case Bitcoin  address. The bitcoin address is nothing but a public key, for each transaction in BTC it is possible to generate a different public key, so each transaction may have a different Bitcoin address.

To make a transaction you do not need to provide any personal data, such as your name and surname. The only data visible on a blockchain will be the public address of your and the recipient wallets, quantity of the transferred BTC and time stamp; nothing more. While banks account transactions only on given weekdays and hours, Bitcoin net does not have such limitations. Everything happens automatically, without third parties involvement. 

Speculative asset

Some people treat BTC is a speculative asset, because of its fluctuate exchange rate. Those, who invested in Bitcoin when it was worth only a few dollars are billionaires these days. However, we must remember that the value of BTC does not only rise, it also decreases. The exchange rates of the all the cryptocurrencies are extremely unstable. Bitcoin investors can be divided into two groups: holders – those, who purchase the cryptocurrency and then keep it in the wallets for years hoping for a  big return, and traders – market players, who only hold on to BTC for short period of time, buy it when the exchange rate decreases and sell when it rises. This way they earn on exchange rate fluctuations. 

Savings protection

Although, keeping your savings in a form of such an unstable asset seems irrational, for many it’s the last resort. When traditional financial systems collapse, people look for alternatives to protect their funds. In such cases, they often turn to Bitcoin, not to use it for transactions or to hope for a return on their investment, but to protect their money from the influence of situation in their country. Forever fluctuating cryptocurrency becomes more valuable to them, than the collapsing fiat money.

Who created BTC? Who’s Satoshi Nakamoto?

Those intriguing questions baffle the cryptocurrency society since the time the Bitcoin was created. Who is the person hiding behind Satoshi Nakamoto codename and why was he/she so concerned about anonymity? Was it indeed just one person? Or perhaps a group of people? I suppose we will never find that out.

Let’s then wonder, why Nakamoto wanted to remain anonymous. Well, cryptocurrency is a kind of a treat to existing financial system. Governments are hostile towards Bitcoin, simply because they cannot control it. They do not enjoy this lack of power at all, so if the creator of BTC was not hiding behind a codename, he would probably be in danger himself. 

11 years ago, this mysterious man published the white book of Bitcoin. Lot of people also call it the Satoshi Nakamoto Manifesto. The document thoroughly explains BTC functions and full technical potential of its net. 

What’s particularly interesting is that throughout the last decade, there were many claiming it’s them, who created the most popular cryptocurrency in the world. However, none of them was able to present evidence sufficient enough, to prove their words. 


Satoshi Nakamoto impersonators

Craig Wright

Everyone in the world of cryptocurrency knows this man as a self-styled Satoshi Nakamoto. He claims to be the father of Bitcoin. However, when called upon to present a prove of his words, he was not able to produce any. Of course, he explained, that he cannot do it, as it would demolish all the past years, when he remained anonymous. Nevertheless, lots of people judged that this means Wright is not who he says he is.

Dorian Nakamoto

The case of Dorian Nakamoto is the exact opposite. In 2014 an American Newsweek journalist conducted a questionable investigation, that led her to Dorian Nakamoto. Wrongly interpreted facts published in the newspaper caused, that right after the article was printed, paparazzi’s swarmed Nakamoto’s house. Dorian was stripped of his privacy, even though he claimed from the very beginning, that he has nothing to do with Bitcoin.

Satoshi Nakamoto Renaissance Holdings

Mid 2019 a marketing company called Satoshi Nakamoto accounted, that after years of quite the BTC creator decided to break the silence. The statement was considered to be very unusual, the real Nakamoto would announce the news himself on a cryptocurrency chat or forum like bitcointalk, rather than using the middleman. The community perceived this whole thing as just a marketing trick and a desire to get recognized. 

Jörg Molt

Another daredevil, that came into the view in 2019 was a German speaker and blockchain and cryptocurrency consultant - Jörg Molt. During one of his conferences, held in India, he introduced himself as Satoshi Nakamoto. Of course, this declaration was met with a great criticism of the cryptocurrency community. He was very quickly announced an imposter.  


Bitcoin mining – what is this about?

As you probably suppose, BTC does not just appear out of the blue. It is extracted with a use of a special equipment, called the cryptocurrency excavator. The process is called Bitcoin mining and the people engaged in it are Bitcoin miners. People outside of the cryptocurrency world most likely have a totally incorrect idea, of what a cryptocurrency mine is. Why is that? Because, in fact, any space, where the excavation equipment is solving complicated mathematical equations can be called a mine. It’s just about getting the reward – the BTC block. The idea image of a Bitcoin miner as a person with a pick in his hands can be put aside then. 

How does the actual BTC mining process runs and how do the cryptocurrency excavators look like? The miners are being awarded with the Proof of Work (PoW). This proof is the Bitcoin. However, to perform this work, miners need equipment with a great computing power. Each piece of equipment has equal chances of digging up BTC. But does it mean that mining for Bitcoin is easy? No at all. In time the difficulty was increasing, at first a simple computer might have been used as an excavator, now a sophisticated equipment is needed. The bigger the computing power of the machine the bigger changes of getting to BTC.

At first, simple CPU processors were used to mine for Bitcoin. The miner would share the computing power of his machine in exchange for BTC. But at that time, no one knew that one day, the cryptocurrency will be so valuable. And so, for a few years since Bitcoin creation it was possible to mine for it, with a use of a laptop or a desktop. But things changed were quickly, in time CPUs were not able to meet the requirements of PoW. They were just not able to perform so many calculations at the same time. That is why graphics cards (GPUs) took their place They could operate on multiple algorithms, but because of less efficiency and higher electricity consumption they soon became unprofitable. And then ASIC (integrated circuit) was introduced. Unlikely the GPUs, which were pretty much used just for computer games and video rendering, ASICs were designed to perform specific actions, in this case mining for Bitcoin.

The evolution of cryptocurrency excavators:




Mathematical equations, that the cryptocurrency excavators must solve, are automatically generated by the Bitcoin net. The more miners join the net and start to compete with each other, the harder the puzzle gets. It takes a long time and a lot of energy to solve it. Also, the quantity of Bitcoin received in return changes – it’s called Bitcoin halving. It takes place every four years, more precisely each 210 000 mined chains. Adapting the difficulty of BTC mining allows for stabilize its emission on a given level. 

Bitcoin halving – what does it mean?

Lately, there's been a lot of talk about Bitcoin halving. What does it actually mean and what is its impact on the cryptocurrency community? It is important to realize, that the halving is not a new thing, it occurs every 4 years since Bitcoin creation. In this article’s chapter about Bitcoin mining there’s a mention on increasing difficulty of BTC excavation. Each time another 210 000 BTC blocks are mined, the miners will receive half less PoW for their future work.

Bitcoin halving will take place till the time all of it is excavated. The last BTC block will probably be mined after year 2140. Why Satoshi Nakamoto invented the BTC halving? The mechanism was intended to balance supply and demand. Imagine all 21 million of BTC were present on the market at once. The demand for it would be much lower and the miners would feel no incentive to keep logging transactions in BTC blockchain. Reducing the prize for excavating BTC eliminates that problem. And with a reduced supply the value of Bitcoin increases. 

How does halving impacts the exchange rate of BTC? No one really knows that. On one hand, many constantly speculates the Bitcoin value will rise, on the other hand others claim it will drop, as it will no longer be profitable to mine for it. However, what happened after past halvings is worth taking a closer look, just to have a better understanding of the consequences.  

First reduction in the value of a prize awarded in return for excavating BTC took place on 28th November 2012. The Bitcoin exchange rate at the time was around 13,42 USD and the halving did not have a major impact on it. However, not long after that, the exchange rate increased to 230 USD. Many claimed, that was because of the rescue action for Cyprus. In 2013 the BTC price rapidly increased, after investors all around Europe started to question the security of banks’ financial systems. The situation in Cyprus was difficult at the time, many citizens of this small island were fighting for their right to access their own cash stored in the country’s banks. Some of them took massive loss on their deposits.  

Next halving took place in 2016. Not much changed then as well. During the occurrence the BTC exchange rate oscillated around 650 USD, week after that around 675 USD. A boom in BTC values was not recorder until December 2017.

What will happen this time? Millions of theories already exist. Most popular one says, that because of the shortage of BTC on the market, its value will increase significantly till the end of 2020.

FAQ on halving and Bitcoin 

When will the last Bitcoin be excavated?

Calculations suggest it will happen after the year 2140. However, it is not possible to predict the date precisely. 

What will happen when all Bitcoin is excavated?

After all the BTC is mined the miners will still receive a reward in a form of transaction fee for logging transactions.

How many Bitcoins a day is excavated?

Each day around 144 blocks are discovered. That gives around 1800 BTC, 12,5 Bitcoin per block.


How much does Bitcoin cost? How to check its price in a chart?

The current value of Bitcoin is around 7 200 USD (as of 20.12.2019, 3:54 PM). In Polish Zloty that’s over 28 000 PLN. How to read the price in a chart? That’s very intuitive! It does not matter which website you are using, they all look similar. The horizontal axis represents time period, you can extend or shorten it from daily to weekly, monthly, yearly etc. up to your own needs and likes. The vertical axis shows the Bitcoin price. The bars located at the bottom of the chart reflect volume of transactions (they are present in professional charts).

Which stock exchange is Bitcoin listed on?

Given the BTC is the most popular cryptocurrency, it is listed on the virtual money stock exchange. These platforms can be divided into two main categories: crypto-crypto stock exchange and crypto-fiat stock exchange. To buy Bitcoin in the first one, the user must be already in possession of another cryptocurrency and use it for payment. These markets do not operate on fiat money such as PLN or USD and they are used by experienced market players, who are already familiar with a cryptocurrency concept. They’re not popular among beginners, who want to purchase Bitcoin using traditional currency. This kind of transactions can be done in crypto-fiat stock exchange.  

Types of BTC stock exchange

Crypto-crypto stock exchange

You can buy Bitcoin only with the use of another cryptocurrency 

Crypto-fiat stock exchange

You can buy Bitcoin using traditional cryptocurrencies
like PLN or USD

Interesting thing: you can also distinguish cryptocurrency stock exchange that are centralized (controlled by a company or an institution) from those decentralized (based on blockchain). You cannot use a transaction bot on the decentralized markets, therefore their transaction volume and liquidity are lower and they are not very popular.

You need to remember, that each cryptocurrency platform differs from the others. Some have simple interfaces, other ones more complicated, some have a very broad offer, others just base on the leading currencies. Before you choose a platform for yourself you need to consider all the aspects. If you want to trade Bitcoin, choose a market with low transaction fees, if you consider a long term invested, pick a one with high liquidity. Take the safety factor into consideration as well. Do not consider the cryptocurrency stock exchange to be a kind of a savings account. Due to the large number of assets stocked on the platform, these markets fall victims to cyberattacks. That also happens to the most renowned ones.

Examples of cryptocurrency stock exchange with Bitcoin listing 

Crypto-fiat stock exchange:

Bitcoin wallet. How to choose?

You probably wonder, how you can acquire BTC, since it does not exist in a physical form. Well, the BTC you purchase will be assigned to the public address of your wallet. Each Bitcoin wallet consist of two keys: private and public.  

Bitcoin wallet

Private key

  • Just for you (do not share it with others)

  • You must it to access your cryptocurrency 

  • Can also be used to confirm transactions

Public key

  • You can share it with others

  • Your Bitcoin balance is assigned to it 

Let’s use a metaphor to better describe the principles of Bitcoin wallet. Image a post box. Only you know the access code (private key), which must be used to open it. Others may drop letters into your box (BTC), because there’s a small hole in it, but they cannot take anything out of it. But if you misplace your access code and it falls into to the hands of a person, who also knows the address of your post box, he can open it and take what’s in. Hence, it’s very important for you to guard your access code (private key) and do not share it with others.

If you lose or forget your code (private key) you will not be able to access your own post box (Bitcoin wallet). There will be no one who could help you, in case it happens. That’s what happened to a number of people, who lost their cryptocurrency.


Bitcoin wallet types

Cold wallets

  • operate in offline mode

  • safest kind of wallets

  • preferred by long term investors, often with large capital

Hot wallets

  • operate in online mode 

  • as they’re constantly connected to the Internet, they are not considered to be safe

  • often chosen by those with small capital


BTC wallets can be divided into two main categories: cold and hot. Choosing a wallet right for you is very important, the safety of your Bitcoin depends on it. 

Bitcoin wallets

Cold BTC wallets

Hardware wallets

  • Present in a physical form. Can look like a pen drive or a small remote controller. 

  • Operate in offline mode, hence considered to be the safest ones

  • They store the private key in a way that allows it to remain safe, even after connecting the wallet to a virus infected computer

  • Examples: Trezor, Ledger

  • They’re not free of charge, you need to pay to use them

  • NOTE: remember to always buy hardware wallets directly from the manufacturer. Only then you can be sure, that no one modified the equipment, which could endanger the Bitcoin in your possession. If you notice, after receiving the package with your wallet, that the wrapping is broken in any way, send a complaint to the producer and demand a new product. 

Paper wallets

  • It’s simply the public and private keys printed on a piece of paper

  • Remember to always generate the keys in an offline environment (without Internet access)

  • They are free of charge

  • Example:

Hot BTC wallets

Desktop wallets

  • You can download them to your computer

  • Work on operating systems like Windows or Linux

  • As they are constantly connected to the Internet, they are considered to be unsafe, your key can be hacked

  • They are free of charge

  • Examples: Exodus, Jaxx

Browser wallets

  • Operate on web browsers

  • They are simply websites you log into

  • They are comfortable to use

  • They are unsafe

  • They are free of charge

  • Example: Blockchain

Mobile wallets

  • These are mobile phones applications

  • Easy alternative to other hot wallet types

  • They are free of charge

  • They are not very safe

  • Example: Mycelium


How to acquire BTC?

Do you want to purchase Bitcoin? There are many options to do that: cryptocurrency exchange stock, online cryptocurrency exchange service or personal sale. The last one calls for caution. It is much safer to use the broker services, even if you’ll need to pay the transaction fee. This way you can be sure the other party to the contract will keep their end of the deal.

You wonder what’s the quickest way to obtain BTC? Use our cryptocurrency exchange service We do not require an arduous process of data verification. You just need to put the number of Bitcoin you want to purchase to the blank field and provide your email address and public address of your wallet. Can’t get easier that that! Just visit us!

How to invest in BTC?

Before you make a decision about investing in Bitcoin make sure your assets will be safe. Store them in a secured place and never share your private keys. Cryptocurrency markets are unstable, BTC exchange rate fluctuates heavily, so never invest funds you are not ready to lose! Try not to give in to emotions, the market if full of FUED (information meant to cause a given emotional response). Stick to your chosen investment method, do not blindly follow the current trends. Avoid FOMO, fear of missing out – on purchasing BTC when the value is raising, on selling it when the price drops heavily. Emotions were never and will never be a good advisor to a cryptocurrency market player.
