What is Bitcoin?

Bitcoin is a digital currency, also known as cryptocurrency. There is no single entity that owns and operates Bitcoin.

Bitcoin is the first payment system that allows the migration of institution-based money to network-based money.

Are there any environmental concerns associated with cryptocurrency mining?

Yes, cryptocurrency mining, particularly for cryptocurrencies like Bitcoin, has raised concerns about its environmental impact. The energy-intensive mining process, coupled with the reliance on fossil fuels in some regions, contributes to carbon emissions and energy consumption. Efforts are being made to explore more sustainable mining practices and the use of renewable energy sources in mining operations.

Can cryptocurrencies be used for everyday purchases?

Cryptocurrencies can be used for everyday purchases at select merchants and online platforms that accept them as a form of payment. However, their acceptance as a widely used medium of exchange is still limited compared to traditional fiat currencies. Efforts are underway to increase cryptocurrency adoption for everyday transactions through payment processors and partnerships with retailers. 

What is a blockchain and how does it relate to cryptocurrencies?

A blockchain is a decentralized and distributed digital ledger that records transactions across multiple computers or nodes. It serves as the underlying technology for cryptocurrencies, enabling transparent and secure transaction verification and record-keeping. Each transaction is added to a block, which is linked to previous blocks, forming a chain of blocks (hence the term "blockchain"). Cryptocurrencies utilize blockchain technology to achieve consensus, immutability, and transparency.

How does the price of cryptocurrencies fluctuate?

The decentralized nature of cryptocurrencies and relatively low liquidity compared to traditional financial markets can contribute to higher price volatility.

How do cryptocurrency wallets work?

Cryptocurrency wallets are software applications or hardware devices that store public and private keys required to access and manage cryptocurrencies. They enable users to send, receive, and store cryptocurrencies securely. Wallets can be classified into different types, including hardware wallets, software wallets (desktop, mobile, or web-based), and paper wallets. Each wallet type has its own security features and trade-offs. 

What are non-fungible tokens (NFTs)?

Non-fungible tokens (NFTs) are unique digital assets that represent ownership or proof of authenticity of a particular item or piece of content.

Can cryptocurrencies replace traditional fiat currencies?
