The Origins of Bitcoin
In 2009, an individual or group known as Satoshi Nakamoto launched the Bitcoin network, introducing the world to cryptocurrency. Nakamoto published a white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System," describing how blockchain technology could enable direct, decentralized transactions without reliance on central authorities like banks.
The identity of Satoshi Nakamoto remains one of crypto's greatest mysteries. No one is entirely sure if this is a person or a group of people. What is known is that Nakamoto's innovation created a financial system that operates independently of traditional banking institutions.
Understanding the Bitcoin Network
Bitcoin is defined as a peer-to-peer electronic cash system that facilitates the transaction of bitcoin between parties without friction. The network operates on a decentralized model, meaning no single person or group controls the whole system. Instead, control is distributed among multiple participants around the world.
People called "miners" help ensure all transactions are fair and recorded on the blockchain. They use computers to solve complex mathematical algorithms through a process known as Proof of Work (PoW), which confirms that transactions are legitimate. For doing this work, miners are rewarded with bitcoin.
The Scarcity of bitcoin (BTC)
One crucial aspect of bitcoin is its limited supply. Satoshi Nakamoto capped the total supply at 21 million, meaning there will never be more than 21 million bitcoins in existence. This built-in scarcity is similar to gold, where the value changes based on supply and demand.
All currencies have an abbreviation. For example, the United States Dollar is also known as USD. Similarly, the abbreviation for bitcoin is BTC. When you see BTC referenced on exchanges or in financial news, it refers to the cryptocurrency unit, not the network itself.
Why the Capitalization Matters
Using the correct capitalization helps communicate clearly about cryptocurrency. When discussing the technology, protocol, or network as a whole, use "Bitcoin" with a capital B. When referring to the currency units themselves, use "bitcoin" with a lowercase b.
For example:
- "The Bitcoin network has never been successfully hacked." (referring to the network)
- "He transferred 2 bitcoin to his wallet." (referring to the currency)
This convention is widely accepted in the cryptocurrency community and helps distinguish between the revolutionary technology and the digital asset it produces.
Key Takeaways
- Bitcoin = network/protocol: The decentralized blockchain system created by Satoshi Nakamoto in 2009
- bitcoin = currency unit: The cryptocurrency used for transactions on the Bitcoin network
- BTC = ticker symbol: The abbreviation used for the bitcoin currency on exchanges and financial platforms
- 21 million cap: The maximum number of bitcoins that will ever exist, creating built-in scarcity

Frequently Asked Questions
Why does capitalization matter for Bitcoin?
Capitalization helps distinguish between Bitcoin, the decentralized blockchain network and protocol, and bitcoin, the digital currency used on that network. Using the correct form improves clarity when discussing cryptocurrency, investing, or blockchain technology. This distinction is widely recognized across the crypto industry, financial media, and exchanges.
When should I use Bitcoin vs. bitcoin in writing?
Use “Bitcoin” with a capital B when referring to the blockchain network, technology, or protocol itself. Use “bitcoin” with a lowercase b when discussing the currency, investment asset, or units of BTC being traded or held. This style convention is commonly used throughout the cryptocurrency industry to avoid confusion between the technology and the asset.
What does BTC stand for?
BTC is the ticker symbol used to represent bitcoin, the cryptocurrency native to the Bitcoin network. Similar to how USD represents the U.S. dollar, BTC is used across exchanges, wallets, trading platforms, and financial news outlets. Investors often see BTC referenced when tracking bitcoin’s price, market performance, or portfolio allocations. Through iTrustCapital, clients can gain exposure to BTC through a tax-advantaged retirement account or a premium custody account.
Who created Bitcoin?
Bitcoin was created by an anonymous individual or group using the pseudonym Satoshi Nakamoto. In 2008, Nakamoto published the Bitcoin white paper, which introduced the concept of a decentralized peer-to-peer electronic cash system powered by blockchain technology. The Bitcoin network officially launched in January 2009 and has since become the largest and most recognized cryptocurrency in the world. Despite years of speculation, Satoshi Nakamoto’s true identity remains unknown.
How many bitcoins will ever exist?
The maximum supply of bitcoin is capped at 21 million coins, a limit built directly into the Bitcoin protocol by Satoshi Nakamoto. This fixed supply is one reason many investors compare bitcoin to scarce assets like gold, as scarcity can influence value over time based on supply and demand dynamics. New bitcoin enters circulation through mining rewards, but the issuance rate decreases approximately every four years during events known as “halvings.”
Can I buy a fraction of a bitcoin?
Yes, bitcoin is highly divisible, meaning investors do not need to purchase a full BTC to gain exposure. Bitcoin can be divided into smaller units called satoshis, with one satoshi equal to 0.00000001 BTC. This flexibility allows investors to buy bitcoin in amounts that fit their budget or investment strategy, regardless of the current market price. Platforms like iTrustCapital allow clients to purchase fractional bitcoin within Crypto IRAs and Premium Custody Accounts, making BTC more accessible to a wider range of investors.
