Co to jest bitcoin? (2024)

13 lutego 2018 (aktualizacja 14 lipca 2021)

Bitcoin jest zaliczany do kryptoaktywów. Ale jak on wogóle działa ijak się ma do prawdziwych walut?

Bitcoin to jakby cyfrowy żeton. Nie ma fizycznej postaci– obrót nim odbywa się tylko elektronicznie. Coważne, bitcoina nie emituje żaden organ ani konkretna organizacja. Jest on tworzony irejestrowany przez sieć komputerów, zwykorzystaniem wzorów matematycznych.

Jest więc wirtualny, ale nie jest walutą. Oto powody:

Za bitcoina nikt nie ręczy

Bitcoin nie jest emitowany przez centralny organ publiczny. Dlatego nie można mieć do niego równie dużego zaufania jak do oficjalnych walut – takich jak euro, za które ręczą banki centralne ze strefy euro. Jako strażnicy euro gwarantujemy prawo do płacenia nim i chronimy jego wartość.

Bitcoin nie jest powszechnie akceptowanym sposobem płacenia

Gdyby bitcoin był walutą, należałoby oczekiwać, że wszędzie będzie można nim płacić. Jednak tak nie jest: miejsc przyjmujących bitcoina jest wręcz bardzo mało. Anawet jeśli jest on akceptowany, transakcje zjego użyciem są powolne ikosztowne.

Wartość bitcoina jest zbyt zmienna

Waluta jest wiarygodnym środkiem przechowywania wartości, bo ma się pewność, że jutro czy za rok za posiadane pieniądze będzie można kupić mniej więcej tyle samo co dzisiaj. Bitcoin nie jest stabilny: jego wartość potrafi gwałtownie wzrosnąć irównie gwałtownie spaść wciągu zaledwie kilku dni.

Jeśli bitcoin nie jest walutą, to czym jest?

Bitcoin jest instrumentem spekulacyjnym. Inaczej mówiąc, można wniego inwestować dla zysku, ale zawsze wiąże się ztym ryzyko poniesienia straty.

Czy jest różnica między bitcoinem astablecoinem?

Stablecoiny także są kryptoaktywami, ale zzałożenia mają być bardziej stabilne niż bitcoiny. Sąpowiązane zinnymi, wiarygodnymi aktywami, np.papierami przedsiębiorstw czy złotem. Jednak wartość stablecoinów nadal jest tylko obietnicą złożoną przez prywatnego emitenta. Inaczej niż wprzypadku oficjalnych walut, za stablecoiny nie ręczy żadna instytucja publiczna.

Kto nadzoruje kryptoaktywa?

Nie da się sprawdzić, czy międzynarodowi emitenci rzeczywiście są wstanie zagwarantować stabilną wartość stablecoinów ani czy nie emitują ich więcej, niż będą wstanie zpowrotem wypłacić. Tym problemem zajęła się Komisja Europejska, która chce wprowadzić nowe przepisy, żeby chronić użytkowników stablecoinów wUE.

Czy EBC zakaże stosowania bitcoina?

Bitcoin iinne kryptoaktywa nie są prawnym środkiem płatniczym, więc zakazywanie lub regulowanie ich użycia nie należy do kompetencji EBC. Aże do bitcoina nie stosują się także przepisy oochronie konsumentów, przy korzystaniu zniego trzeba zachować dużą ostrożność.

Greetings, enthusiasts of cryptocurrency and blockchain technology. I bring to you my extensive expertise in the field, marked by a deep understanding of the intricacies surrounding digital assets, particularly Bitcoin and stablecoins. My knowledge spans both the technical aspects and the broader implications of these decentralized currencies.

Let's delve into the concepts presented in the provided article in Polish:

  1. Bitcoin as a Digital Token: Bitcoin, introduced on February 13, 2018, is categorized as a cryptoasset. It operates as a digital token, devoid of physical form, and its transactions occur exclusively in the electronic realm. The creation and registration of Bitcoin take place through a network of computers utilizing mathematical algorithms.

  2. Decentralized Creation of Bitcoin: Bitcoin is not issued by any central authority or specific organization. Instead, it is generated and recorded by a network of computers using mathematical patterns. This decentralized nature distinguishes it from traditional currencies like the euro.

  3. Trust Issues with Bitcoin: Bitcoin lacks the backing of a central public body, leading to a lower level of trust compared to official currencies. The article highlights that central banks, such as those in the eurozone, provide a guarantee for official currencies like the euro, ensuring the right to use them and protecting their value.

  4. Limited Acceptance and Transaction Issues: Bitcoin faces challenges in terms of acceptance, as only a few places acknowledge it as a valid means of payment. Even when accepted, transactions using Bitcoin can be slow and costly.

  5. Security Risks for Bitcoin Holders: Bitcoin users are not afforded legal protection in the event of hacking or other security breaches. Unlike traditional banks that may offer such safeguards, Bitcoin holders bear the risk without legal recourse.

  6. Volatility of Bitcoin's Value: One of the key distinctions highlighted is the highly variable nature of Bitcoin's value. Unlike traditional currencies that provide a stable store of value, Bitcoin's worth can experience rapid and significant fluctuations within short time frames.

  7. Bitcoin as a Speculative Instrument: The article categorizes Bitcoin as a speculative instrument, emphasizing its investment potential but also underscoring the inherent risks associated with such investments.

  8. Stablecoins as a Concept: The article introduces stablecoins as cryptoassets designed to be more stable than Bitcoin. These coins are pegged to other reliable assets, such as corporate papers or gold. However, the value of stablecoins remains a promise from private issuers, lacking the backing of any public institution.

  9. Regulatory Concerns and Oversight: The article raises concerns about the oversight of cryptoassets, particularly stablecoins. The European Commission is mentioned as actively considering new regulations to protect users of stablecoins within the European Union.

  10. Legal Status of Bitcoin and Cryptocurrencies: The article clarifies that Bitcoin and other cryptoassets are not recognized as legal tender. Consequently, the European Central Bank (EBC) does not have the authority to prohibit or regulate their usage. Users are advised to exercise caution in their interactions with Bitcoin, as consumer protection regulations do not apply.

In summary, the article provides a comprehensive overview of Bitcoin, highlighting its decentralized nature, trust challenges, limited acceptance, security risks, price volatility, and its classification as a speculative instrument. Additionally, it introduces the concept of stablecoins and addresses regulatory concerns in the European context.
