Bitcoin is the world’s first cryptocurrency and blockchain.
Bitcoin was first described in a white paper published by Satoshi Nakamoto in October, 2008. Nakamoto is believed to be a also known as for the individual or group responsible for Bitcoin as there is no wedding album of a computer scientist by this name prior to the opening of Bitcoin in 2009.
At the time, Satoshi claimed to be a 37 year-old man bustling in Tokyo, Japan. The translation of his publicize offers tempting insights: satoshi means “clear-thinking” or “wise,” naka means “inside” or “relationship,” and moto means “the origin” or “the foundation.” Taken together, it could be translated as “thinking simply inside the foundation.”
Satoshi continued to update the Bitcoin source code until 2010 and wrote hundreds of blog posts in flawless English totalling 80,000 words, roughly the length of a novel. Satoshis’ first say used American spellings, however, every subsequent read out used British spellings and colloquialisms. His writing timestamps don’t narrowing to any particular get older zone.
On the 23rd of April, 2011, Satoshi disappeared from the Internet, telling a developer in an email that he has « moved onto new things. » Whoever Satoshi is, he is considered a polymath who possesses extensive knowledge with adulation to computer programming, economics, cryptography, and peer-to-peer networking.
Bitcoin was born during the 2008 Financial Crisis. To commemorate this moment in time, Satoshi embedded a Times of London newspaper headline into the metadata of the first block of the Bitcoin blockchain, known as the Genesis Block. It reads: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.”
Token
Bitcoin (with a lowercase “b”) or BTC is the digital asset token of the Bitcoin network (Bitcoin similar to a capital “B”). All BTC balances and transactions are recorded on the Bitcoin blockchain. The smallest subunit of BTC is the “satoshi,” which is named after Bitcoin’s pseudonymous creator, Satoshi Nakamoto. One satoshi is equal to 10-8 BTC or one hundred-millionth of a BTC (0.00000001 bitcoin). Bitcoin can be bought and sold for fiat currency or further digital currencies.
Bitcoin can be purchased upon a cryptocurrency dispute and stored in a crypto billfold and custodian in the aerate of Gemini.
Supply
The supply of bitcoin is deterministic and total at 21 million BTC. The supply schedule is embedded in the Bitcoin protocol.
Bitcoin Mining
Satoshi’s major breakthrough was solving the The Byzantine Generals’ Problem. The Bitcoin mining algorithm that Satoshi proposed in the Bitcoin white paper demonstrated how a network of computers concerning the world could reach consensus when each further and agree upon something, even if positive computers were bad actors upon the network a pain to confuse the others.
This consensus mechanism allows the Bitcoin network to agree upon which bitcoin transactions are valid, thereby solving the “double-spend” problem and ensuring that one bitcoin isn’t spent on zenith of once by the same person. As a result, it safeguards the integrity of the Bitcoin blockchain, a compilation of all bitcoin balances and transactions, without the dependence for a trusted third party.
Bitcoin’s consensus mechanism uses a proof of work algorithm. Specifically, miners must solve math puzzles using the SHA-256 hash algorithm of the Secure Hash Algorithm 2 (SHA-2) family. By committing computational capability towards solving the Bitcoin mining algorithm, miners audit and insist the transactions of the Bitcoin network. The more computer skill a miner brings to bear on the Bitcoin network, the more likely she or he is to solve the proof of discharge duty algorithm and win the bitcoin that the network rewards to the miner who writes the newest block to the Bitcoin blockchain.
Characteristics
Bitcoin is often called “digital gold” because its traits alongside resemble those of gold. In 2015, a U.S. Federal declare concluded in the Coinflip, Inc. order that bitcoin was legally a “commodity” under the Commodities and Exchange Act.
The subsequently table offers a comparison surrounded by bitcoin and gold:
Bitcoin Halving or Halvening
The supply schedule of bitcoin is deflationary. This schedule — embedded in the Bitcoin protocol — dictates that every time a miner successfully writes a other block to the blockchain (i.e., solves the proof of feign puzzle), that miner shall receive a set number of bitcoin called the « block reward. » The Bitcoin protocol sets and adjusts the mining difficulty so that miners will be dexterous to win the block compensation roughly all 10 minutes. The block recompense is how anything new bitcoin are issued or minted, and how anything bitcoin in circulation have come into existence.
Every 210,000 blocks — roughly every 4 years — the block recompense is condensed by half, an business often referred to as the « the halvening » or “the halving.” When Bitcoin launched in 2009, the initial block return was 50 bitcoin. On November 25, 2012, the first halvening occured, halving the block compensation from 50 to 25 bitcoin. On July 10, 2016, the second halvening occured, halving the block recompense from 25 to 12.5 bitcoin. The third halvening is usual to happen in May, 2020 and will edit the block return from 12.5 to 6.25 bitcoin.
The block reward will continue to undergo halvings until it reaches 0. This is estimated to happen sometime in the year 2140. At this point in time, there will be a sum of 21 million bitcoin in circulation.

Total Supply
21 million by 2140 (approx.)
Block Reward

Halving event
Every 4 years (aprrox.) Every 210,000 blocks until total supply reaches 21 million (fixed).
HODL, HODLing, and HODLers
HODL is a slang in the crypto freshen that refers to the engagement of buying and holding bitcoin. The etymology of the term can be traced urge on to a misspelling of the word “hold” in a proclamation posted to Bitcointalk’s Bitcoin Forum in 2013 and titled I AM HODLING. Some, however, have incorrectly assumed that the word is an acronym for the phrase “hold upon for dear life.”
HODL has become a prominent internet meme and rallying cry for the Bitcoin community, especially during become old of tall volatility and large price declines. Those who HODL are called HODLers and are said to be HODLing. The basic principle astern HODLing is to take a long term buy and hold view towards bitcoin as adjacent to a short-term one that involves trading in and out of bitcoin upon a daily, weekly, or monthly basis. HODLING avoids having to correctly period trades with the publicize and react to price volatility, which can result in buying tall or selling low. It does, however, require strong conviction and resolve during make public downturns.
HOLDING may also result in tax promote related to capital asset treatment per IRS Virtual Currency Guidance (Please Note: nothing contained herein should be considered or construed as tax advice of any kind. This content is provided for recommendation purposes only).
The HODL strategy appeals to Bitcoin maximalists who tolerate that bitcoin may ultimately replace fiat currencies. It in addition to an important component of “stacking sats,” #stackingsats, or “stacking satoshis,” a popular investment strategy based upon the premise that accumulating even little amounts of bitcoin (a satoshi is the smallest subunit) over mature will prove to be a vital investment in the long control if bitcoin goes “to the moon!” — a popular declare metaphor and trope used by bitcoiners to describe bitcoin price appreciation.
The Bitcoin Pizza and Bitcoin Pizza Day
The bitcoin pizza refers to the first get older bitcoin was used to buy a real good. On May 22, 2010, a programmer in Florida named Laslo Hanyecz (now referred to as the “Bitcoin Pizza Guy”) purchased two Papa John’s pizzas for 10,000 bitcoin; a day now referred to as Bitcoin Pizza Day. Initially, Laslo posted a proclamation titled « Pizza for bitcoins? » on Bitcointalk’s Bitcoin Forum. An 18-year old-fashioned named Jeremy Studivant responded under the handle “Jercos” and the two well along consummated the transaction beyond Internet Relay Chat (IRC). Afterwards, Hanyecz exclaimed: « I just want to bank account that I successfully traded 10,000 bitcoins for pizza. Thanks jercos! »
Lalso paid for the two pizzas using bitcoin that he mined afterward his personal computer. At the time, the bitcoin that exchanged hands was valued at approximately $30 dollars. Since then, the value of that thesame amount of bitcoin has grown exponentially (worth over $90 million dollars as of May 22, 2020), making this the most costly pizza ever purchased in the world. Every year on May 22, the Bitcoin community commemorates Bitcoin Pizza Day. This historical daylight highlights the deflationary plants of bitcoin and its increase of value properties.
