The most important thing about Bitcoin
What is Bitcoin?

What is Bitcoin?

Satoshi Nakamoto, whose true identity remains a secret to this day and could therefore be an individual or a group, developed the cryptocurrency Bitcoin (BTC) in 2007. As a decentralized monetary system, the Bitcoin exchange rate remains unaffected by governments or financial institutions.

In this peer-to-peer (person-to-person) network, trillions of dollars are moved every year without the involvement of a third party. Essentially, the Bitcoin network is a collection of software programs running simultaneously on tens of thousands of computers around the world. They maintain and update a shared ledger called a blockchain.

While Bitcoin is best known for the ingenious interplay of different technologies, the key feature is ultimately the power that comes from its growing user base.

You can find a brief introduction, accompanied by graphics, in our Coinfinity Bitcoin Blinks. There are also many other Bitcoin topics that are explained very simply.
Bitcoin simply explained

Bitcoin simply explained

In the following, we would like to explain this very complex and multi-layered network in more detail and yet as simply as possible:

Bitcoin is a scarce, digital asset that cannot be devalued by increasing the number of units like our national currencies (e.g. euros or US dollars). The total amount of Bitcoin is fixed (21 million units) and the issuance schedule is known, secure and unchangeable.

Ownership is recorded in a register similar to that of publicly traded shares, which is public, transparent and decentralized, unlike the custodian. The blockchain.

The blockchain is verified and managed by a global network of interconnected servers and computers, the Bitcoin network. Bitcoin mining is used both to issue new coins and to protect the network from attack.

The Bitcoin network relies on advanced encryption techniques and market incentives rather than a central authority. It is the most powerful computer network in the world in every respect. It has never been hacked or interrupted.

For the first time in our history, everyone can own and save an asset that is truly limited, decentralized, censorship-resistant, borderless and non-confiscable.

Frequently asked questions

Why should you use Bitcoin?

There are many good reasons to get involved with Bitcoin. Due to its decentralized nature, many people trust the monetary properties of Bitcoin more than they do with other currencies. Bitcoin also differs from other cryptocurrencies because it is a system that is so widely distributed that it is probably the only place you can speak of a network that cannot be influenced by central authorities.

Why should you use Bitcoin?

Bitcoin as digital money

Bitcoin can be used in a similar way to other currencies. You can use it to pay for goods or services. To send Bitcoin, the sender only needs to know the Bitcoin address of the recipient. This means you can send value around the world at any time of day or night, without a third party (such as a bank).

Bitcoin as a store of value

As is often the case with the organic creation of new money, the most important property currently used for Bitcoin is that of a store of value. Like gold, for example, Bitcoin is often seen as a hedge against inflation and as an appreciating asset that retains its value or even gains purchasing power over time. For this reason, Bitcoin is often referred to as "digital gold".

However, due to its relatively recent history and much lower liquidity in the market, the Bitcoin price fluctuates relatively strongly. Even if this high volatility has meant a long-term trend of increasing value in the past, no one can say with certainty that these fluctuations will have a similar effect in the future.

Bitcoin as an object of speculation

As already mentioned, Bitcoin is characterized by strong price fluctuations. This also makes Bitcoin an interesting speculative asset for traders and gamblers. In our view, however, short-term investments are not recommended for "non-professionals". A long-term savings strategy has not only proven successful in the past, but is also much less stressful.

More important facts about Bitcoin

Satoshi Nakamoto launched Bitcoin in 2007 and published the revolutionary white paper in the Cypherpunk mailing list in 2008.

The Bitcoin system has been running since 2009 and produces a new block approximately every 10 minutes.

A maximum of 21,000,000 BTC coins can be mined through mining and the proof-of-work consensus mechanism.

Bitcoin presents itself as an attack-proof, pseudonymous and comparative inflation-proof currency.

Renowned companies such as Tesla, MicroStrategy and Block.One have invested considerable sums of money in Bitcoin.

The last part of Bitcoin is expected to be mined in 2140.

A halving takes place every four years, i.e. the amount of Bitcoin issued is halved. The next halving will take place in April 2024.

The encryption of the blockchain minimizes the risk of a hack and makes the currency practically unassailable.

Frequently asked questions

Price development and market dynamics of Bitcoin

The Bitcoin price results from the dynamic balance between supply and demand. As an autonomous monetary system, Bitcoin remains unaffected by banks and government influence. Price increases typically follow an increase in demand, although various factors, including geopolitical and economic events, can cause fluctuations.

Bitcoin price development

Bitcoin price: milestones and important events

Starting with the first documented Bitcoin price of USD 0.0008 per coin, the currency has had a diverse price history. One notable moment was the purchase of two pizzas for 10,000 BTC in 2010. In successive years, the Bitcoin price has experienced significant peaks and troughs, including the all-time high of USD 69,045 per coin in November 2021.

Here are some standout events in the Bitcoin price history:

2008: $0.0008/BTC
2010: $0.03/BTC
2013: Exceeding $1,000/BTC for the first time
2017: Price peaks at $19,666/BTC
2018: A low of under $3,000/BTC
2022: Price falls and rises again above 20,000 $/BTC
2023: Bitcoin's price rises by 60% in the first half of the year

Companies, investors and Bitcoin adoption

Over the years, Bitcoin has become increasingly popular not only with private investors, but also with large companies and asset management institutions. Major events such as PayPal's acceptance of Bitcoin and extensive investments by Tesla had a significant impact on the price, driving it to its all-time high of around EUR 60,000 in November 2021.

Regulations, bans and the future of Bitcoin

The year 2022 brought some new regulatory developments, such as planned government regulations and a complete ban on Bitcoin in China. At the same time, the collapse of FTX and the Terra blockchain occurred, leading to great uncertainty in the market. Once again, many people had to learn that they should store their Bitcoin themselves in order to minimize the necessary trust in institutions. For this reason, we always send Bitcoin purchases directly to your own wallet.

Lessons and perspectives from the Bitcoin price history

Bitcoin's historical price movements reveal high volatility, driven by massive changes in demand, while supply is planned and static. Although positive price movements have been observed, past performance is not a predictor of future results. However, with recently released financial products such as the Blackrock Bitcoin ETF, it is likely that many more people and especially institutions will follow the idea of Bitcoin in the near future.

Frequently asked questions

What influences the Bitcoin price?

What are the factors influencing the price of Bitcoin, the most prominent cryptocurrency? With a remarkable market capitalization that currently graces the top of the crypto world, Bitcoin manifests itself as an economic force, but also with sometimes strong fluctuations, measured in fiat currencies such as the Euro.

What influences the Bitcoin price

Inflation and manipulation of the Bitcoin price

The development of Bitcoin in the financial world is remarkable and at the same time complex, characterized by a fixed maximum quantity and predictable halvings. The current and future issue rate of new Bitcoin is known and can therefore be planned. As a fixed supply therefore meets a sometimes very fluctuating demand, the Bitcoin price is often characterized by large fluctuations.

Other factors that can strongly influence the Bitcoin price in the short term are over-interpreted news reports or statements by well-known personalities. In the long term, however, these factors do not really have a massive impact on the market price.

Bitcoin in everyday use: An experiment in El Salvador

Bitcoin is now also anchored in everyday life in El Salvador, where it functions as a legitimate means of payment alongside the US dollar. This decision enables freedom from international financial structures and fears of inflation, but at the same time exposes the country's level of prosperity to a certain extent to the volatile nature of the BTC exchange rate. It is therefore important for the national government to find a challenging balance between financial freedom and stability.

A look at Bitcoin's security

When it comes to the security of Bitcoin, the blockchain with its almost impenetrable structure is insurmountable for potential attackers. However, exchanges and service providers that offer their customers the storage of Bitcoin open up a space for potential threats. Incidents such as the theft of 7,000 Bitcoin from the Binance exchange in May 2019 unfairly cast Bitcoin in a bad light. However, such attacks are not even possible on the Bitcoin blockchain itself, but only when custodians holding customers' assets are attacked. Those who hold their Bitcoin themselves, for example by buying it from Coinfinity, take personal responsibility and do not run the risk of becoming the victim of such a hacker attack.

In the US, regulation was like the Wild West at times. But at Coinfinity, we value transparency: as a company regulated by the FMA (Austrian Financial Market Authority), we stand in contrast to opaque companies that carelessly handle customer funds. In an age where technology and security complement each other, well-known Bitcoin companies such as Blockstream, Lightning Labs and Spiral are investing heavily in the further development and perfection of Bitcoin.

Focus on security: How investors stay protected

Careful selection and storage of wallets is crucial to protect investors' crypto assets. In this context, strong passwords and awareness of potential threats also play an essential role in protecting one's crypto wallet from phishing attacks and other fraudulent activities.

These facets show that the journey to Bitcoin is multi-layered and multi-faceted. It is paved with challenges and opportunities that captivate both investors and observers. In this ongoing dialog between technological progress, market manipulation and real-world application practices, Bitcoin remains a fascinating object as a digital store of value and censorship-resistant currency.
