What Is Bitcoin (BTC)?
Bitcoin is a decentralized cryptocurrency originally described in a 2008 whitepaper by a person, or group of people, using the alias Satoshi Nakamoto. It was launched soon after, in January 2009.
Bitcoin is a peer-to-peer online currency, meaning that all transactions happen directly between equal, independent network participants, without the need for any intermediary to permit or facilitate them. 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.”
Some concepts for a similar type of a decentralized electronic currency precede BTC, but Bitcoin holds the distinction of being the first-ever cryptocurrency to come into actual use.
Who Are the Founders of Bitcoin?
Bitcoin’s original inventor is known under a pseudonym, Satoshi Nakamoto. As of 2021, the true identity of the person — or organization — that is behind the alias remains unknown.
On October 31, 2008, Nakamoto published Bitcoin’s whitepaper, which described in detail how a peer-to-peer, online currency could be implemented. 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.”
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. 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. The first known Bitcoin commercial transaction occurred on May 22, 2010, when programmer Laszlo Hanyecz traded 10,000 Bitcoins for two pizzas. At Bitcoin price today in mid-September 2021, those pizzas would be worth an astonishing $478 million. 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.
However, while Nakamoto was the original inventor of Bitcoin, as well as the author of its very first implementation, he handed the network alert key and control of the code repository to Gavin Andresen, who later became lead developer at the Bitcoin Foundation. Over the years a large number of people have contributed to improving the cryptocurrency’s software by patching vulnerabilities and adding new features.
Bitcoin’s source code repository on GitHub lists more than 750 contributors, with some of the key ones being Wladimir J. van der Laan, Marco Falke, Pieter Wuille, Gavin Andresen, Jonas Schnelli and others.
What Makes Bitcoin Unique?
Bitcoin’s most unique advantage comes from the fact that it was the very first cryptocurrency to appear on the market.
It has managed to create a global community and give birth to an entirely new industry of millions of enthusiasts who create, invest in, trade and use Bitcoin and other cryptocurrencies in their everyday lives. The emergence of the first cryptocurrency has created a conceptual and technological basis that subsequently inspired the development of thousands of competing projects.
The entire cryptocurrency market — now worth more than $2 trillion — is based on the idea realized by Bitcoin: money that can be sent and received by anyone, anywhere in the world without reliance on trusted intermediaries, such as banks and financial services companies.
Thanks to its pioneering nature, BTC remains at the top of this energetic market after over a decade of existence. 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 is owing in large part to growing institutional interest in Bitcoin, and the ubiquitousness of platforms that provide use-cases for BTC: wallets, exchanges, payment services, online games and more.

How Much Bitcoin Is in Circulation?
Bitcoin’s total supply is limited by its software and will never exceed 21,000,000 coins. New coins are created during the process known as “mining”: as transactions are relayed across the network, they get picked up by miners and packaged into blocks, which are in turn protected by complex cryptographic calculations.
As compensation for spending their computational resources, the miners receive rewards for every block that they successfully add to the blockchain. At the moment of Bitcoin’s launch, the reward was 50 bitcoins per block: this number gets halved with every 210,000 new blocks mined — which takes the network roughly four years. As of 2020, the block reward has been halved three times and comprises 6.25 bitcoins.
Bitcoin has not been premined, meaning that no coins have been mined and/or distributed between the founders before it became available to the public. However, during the first few years of BTC’s existence, the competition between miners was relatively low, allowing the earliest network participants to accumulate significant amounts of coins via regular mining: Satoshi Nakamoto alone is believed to own over a million Bitcoin.
Mining Bitcoins can be very profitable for miners, depending on the current hash rate and the price of Bitcoin. While the process of mining Bitcoins is complex, we discuss how long it takes to mine one Bitcoin on CoinMarketCap Alexandria — as we wrote above, mining Bitcoin is best understood as how long it takes to mine one block, as opposed to one Bitcoin. As of mid-September 2021, the Bitcoin mining reward is capped to 6.25 BTC after the 2020 halving, which is roughly $299,200 in Bitcoin price today.
How Is the Bitcoin Network Secured?
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.
Bitcoin Energy Consumption
Over the past few decades, consumers have become more curious about their energy consumption and personal effects on climate change. When news stories started swirling regarding the possible negative effects of Bitcoin’s energy consumption, many became concerned about Bitcoin and criticized this energy usage. A report found that each Bitcoin transaction takes 1,173 KW hours of electricity, which can “power the typical American home for six weeks.” Another report calculates that the energy required by Bitcoin annually is more than the annual hourly energy usage of Finland, a country with a population of 5.5 million.
The news has produced commentary from tech entrepreneurs to environmental activists to political leaders alike. In May 2021, Tesla CEO Elon Musk even stated that Tesla would no longer accept the cryptocurrency as payment, due to his concern regarding its environmental footprint. Though many of these individuals have condemned this issue and move on, some have prompted solutions: how do we make Bitcoin more energy efficient? Others have simply taken the defensive position, stating that the Bitcoin energy problem may be exaggerated.
At present, miners are heavily reliant on renewable energy sources, with estimates suggesting that Bitcoin’s use of renewable energy may span anywhere from 40-75%. However, to this point, critics claim that increasing Bitcoin’s renewable energy usage will take away from solar sources powering other sectors and industries like hospitals, factories or homes. The Bitcoin mining community also attests that the expansion of mining can help lead to the construction of new solar and wind farms in the future.
Furthermore, some who defend Bitcoin argue that the gold and banking sector — individually — consume twice the amount of energy as Bitcoin, making the criticism of Bitcoin’s energy consumption a nonstarter. Moreover, the energy consumption of Bitcoin can easily be tracked and traced, which the same cannot be said of the other two sectors. Those who defend Bitcoin also note that the complex validation process creates a more secure transaction system, which justifies the energy usage.
Another point that Bitcoin proponents make is that the energy usage required by Bitcoin is all-inclusive such that it encompasses the process of creating, securing, using and transporting Bitcoin. Whereas with other financial sectors, this is not the case. For example, when calculating the carbon footprint of a payment processing system like Visa, they fail to calculate the energy required to print money or power ATMs, or smartphones, bank branches, security vehicles, among other components in the payment processing and banking supply chain.
What exactly are governments and nonprofits doing to reduce Bitcoin energy consumption? Earlier this year in the U.S., a congressional hearing was held on the topic where politicians and tech figures discussed the future of crypto mining in the U.S, specifically highlighting their concerns regarding fossil fuel consumption. Leaders also discussed the current debate surrounding the coal-to-crypto trend, particularly regarding the number of coal plants in New York and Pennsylvania that are in the process of being repurposed into mining farms.
Aside from congressional hearings, there are private sector crypto initiatives dedicated to solving environmental issues such as the Crypto Climate Accord and Bitcoin Mining Council. In fact, the Crypto Climate Accord proposes a plan to eliminate all greenhouse gas emissions by 2040, And, due to the innovative potential of Bitcoin, it is reasonable to believe that such grand plans may be achieved.
What Is Bitcoin’s Role as a Store of Value?
Bitcoin is the first decentralized, peer-to-peer digital currency. One of its most important functions is that it is used as a decentralized store of value. In other words, it provides for ownership rights as a physical asset or as a unit of account. However, the latter store-of-value function has been debated. Many crypto enthusiasts and economists believe that high-scale adoption of the top currency will lead us to a new modern financial world where transaction amounts will be denominated in smaller units.
The smallest units of Bitcoin, 0.00000001 BTC, are called Satoshis (or Sats in short), in a nod to the pseudonymous creator. At Bitcoin price now, 1 Satoshi is equivalent to roughly $0.00048.
The top crypto is considered a store of value, like gold, for many — rather than a currency. This idea of the first cryptocurrency as a store of value, instead of a payment method, means that many people buy the crypto and hold onto it long-term (or HODL) rather than spending it on items like you would typically spend a dollar — treating it as digital gold.
Crypto Wallets
The most popular wallets for cryptocurrency include both hot and cold wallets. Cryptocurrency wallets vary from hot wallets and cold wallets. Hot wallets are able to be connected to the web, while cold wallets are used for keeping large amounts of coins outside of the internet.
Some of the top crypto cold wallets are Trezor, Ledger and CoolBitX. Some of the top crypto hot wallets include Exodus, Electrum and Mycelium.
