Bitcoin can be used for a variety of purposes, including everyday transactions, as a store of value, or for investment. A wallet is needed to use Bitcoin and it consists of a public key, which is used to send and receive payments, and a private key, which is used to control the wallet. The birth of Bitcoin was the genesis of an entirely new asset class, and a huge step away from traditional, centrally controlled money. For instance, the Iranian government initially opposed cryptocurrencies, but later began using them to circumvent sanctions. El Salvador still describes bitcoin as “legal tender”, but its acceptance is no longer obligitory (as it is with the US dollar) and the El Salvador government no longer accepts bitcoin for payment of taxes or fees. In 2025, El Salvador’s government revoked bitcoin’s status as legal tender currency in order to comply with conditions set by the IMF for a loan.
Meanwhile, in countries facing economic isolation or hyperinflation, residents increasingly explore cryptocurrency as a vital store of value, despite official discouragement. This signals increasing political legitimacy, with some state governments also exploring Bitcoin reserve legislation. While the initiative attracted international controversy and mixed results, it firmly established Bitcoin in global policy discussions. The regulatory approval of spot Bitcoin ETFs that hold actual Bitcoin in the United States and other major markets marked a significant milestone.
Bitcoin is secured with the SHA-256 algorithm, which belongs to the SHA-2 family of hashing algorithms, which is also used by its fork Bitcoin Cash (BCH), as well as several other cryptocurrencies. As compensation for spending their computational resources, the miners receive rewards for every block that they successfully add to the blockchain. Bitcoin’s total supply is limited by its software and will never exceed 21,000,000 coins. Even after Bitcoin has lost its undisputed dominance, it remains the largest cryptocurrency, with a market capitalization that surpassed the $1 trillion mark in 2021, after Bitcoin price hit an all-time high of $64,863.10 on April 14, 2021. This event is now known as “Bitcoin Pizza Day.” In July 2010, Bitcoin first started trading, with the Bitcoin price ranging from $0.0008 to $0.08 at that time.
Bitcoin’s groundbreaking features unlock innovative applications that were previously unattainable by any traditional payment network. Bitcoin operates on an open-source framework, with its architecture fully transparent; no single entity governs it, and participation is open to all. By March 2025, El Salvador’s international reserves included approximately $550 million in Bitcoin—roughly 6,102 coins.
If you are new to crypto, use CoinMarketCap’s own educational portal — Alexandria — to learn how to start buying Bitcoin and other cryptocurrencies. However, there are times when different countries and exchanges show different prices and understanding how much Bitcoin is will be a function of a person’s location. The prices of all cryptocurrencies are quite volatile, meaning that anyone’s understanding of how much Bitcoin is will change by the minute. According to data by the University of Cambridge, China is now the second-biggest contributor to Bitcoin’s global hash rate, only behind the United States. Surprisingly, the anti-crypto stance of the Chinese government has done little to stop the industry.
Addresses and transactions
Multiple adoption vectors including ETF approvals, corporate treasury holdings, and government recognition have legitimized Bitcoin as an investable asset class and alternative monetary system. This enables micropayments with fees measured in satoshis and confirmation times in seconds. This narrative has been reinforced by mainstream adoption, including the approval of spot Bitcoin ETFs and the acquisition of BTC as a treasury asset by major corporations. No Meteor Profit official website government, corporation, or individual can control the network, freeze accounts, or prevent transactions, making it particularly valuable in regions with unstable currencies or authoritarian governments. While exchanges provide trading convenience, they control your private keys, and major exchange failures like Mt. Gox (2014) and FTX (2022) resulted in major customer fund losses. The first miner to solve the puzzle adds the next block and receives newly minted bitcoins plus transaction fees.
Transactions are grouped into blocks, with each block containing a cryptographic hash of the previous block, creating an immutable chain. This ledger is distributed across thousands of computers globally, with each node maintaining an identical copy. Bitcoin operates as a decentralized peer-to-peer network where users exchange value directly without intermediaries.

Bitcoin Halving
The first known Bitcoin commercial transaction occurred on May 22, 2010, when programmer Laszlo Hanyecz traded 10,000 Bitcoins for two pizzas. Bitcoin price was $0 when first introduced, and most Bitcoins were obtained via mining, which only required moderately powerful devices (e.g. PCs) and mining software. Just two months later, on January 3, 2009, Nakamoto mined the first block on the Bitcoin network, known as the genesis block, thus launching the world’s first cryptocurrency. They proposed to use a decentralized ledger of transactions packaged in batches (called “blocks”) and secured by cryptographic algorithms — the whole system would later be dubbed “blockchain.” Bitcoin was created, according to Nakamoto’s own words, to allow “online payments to be sent directly from one party to another without going through a financial institution.”
Peer-To-Peer Money Matters More Than You’d Think
Nakamoto actively developed Bitcoin and communicated with the early community until mid-2010, when they handed over control of the network and disappeared from public view. The first Bitcoin block, known as the genesis block, was mined on January 9, 2009, marking the official launch of the Bitcoin network. Bitcoin is the world’s first decentralized cryptocurrency that enables peer-to-peer electronic cash transactions without intermediaries like banks or governments. As the first digital currency to enable direct transfers of value without intermediaries, Bitcoin has pioneered a new approach to money.
As of 2018update, the overwhelming majority of bitcoin transactions took place on cryptocurrency exchanges. As of 2023, the US government owned more than $5 billion worth of seized bitcoin. Since 2020, Iran has required local bitcoin miners to sell bitcoin to the Central Bank of Iran, allowing the central bank to use it for imports. Bloomberg reported that bitcoin was being used for large-item purchases on the site Overstock.com and for cross-border payments to freelancers. Because of its decentralized nature and its global presence, regulating bitcoin is difficult. Per some researchers, as of 2015update, bitcoin functions more as a payment system than as a currency.
Officials debated the ongoing shift from coal to crypto mining, focusing on New York and Pennsylvania’s coal plants being converted into mining facilities. How are governments and charitable organizations addressing Bitcoin’s energy consumption? Bitcoin advocates argue that its energy consumption encompasses every stage—from creation and security to usage and transfer—making it a holistic requirement. Critics of Bitcoin’s energy use also highlight that its rigorous validation process strengthens security, rationalizing the resource demands. Currently, miners are predominantly using clean energy, with estimates placing Bitcoin’s renewable energy share between 40% and 75%. In May 2021, Elon Musk, Tesla’s CEO, announced the company would no longer accept Bitcoin payments, citing environmental concerns.
Miners group and broadcast new transactions into blocks, which are then verified by the network. The mining process in bitcoin involves maintaining the blockchain through computer processing power. As in a cash transaction, the sum of inputs can exceed the intended sum of payments. Using multiple inputs is similar to using multiple coins in a cash transaction. 5 An address may encode the hash of a bitcoin script that specifies more complex requirements to spend the funds.
Proponents counter that this energy expenditure is justified to secure a global, decentralized financial system. Bitcoin’s security is fundamentally rooted in the SHA-256 cryptographic hash function, a proven algorithm also used to secure critical government and internet infrastructure. Users control their Bitcoin through private keys — cryptographic codes that authorize transactions and prove ownership. New blocks are added approximately every 10 minutes through mining, where specialized computers compete to solve complex mathematical puzzles.
