No one knows. Not conclusively, at any rate. Satoshi Nakamoto is the name associated with the person or group of people who released the original Bitcoin white paper in 2008 and worked on the original Bitcoin software that was released in 2009. The Bitcoin protocol requires users to enter a birthday upon signup, and we know that an individual named Satoshi Nakamoto registered and put down April 5 as a birth date. And that's about it.
Speculation drives numbers. Many Bitcoin users are holding onto their bitcoins in hopes of selling them off for an enormous profit one day. With news articles portraying Bitcoin millionaires as lucky kids who got in early, you can’t really blame them. For example, if you had spent your $5 latte money on 2,000 bitcoins one morning in 2010, they would be worth about $5.4 million today. Makes you really wish you’d managed your Starbucks budget better, doesn’t it?
Bitcoin is a digital currency created in 2009. It follows the ideas set out in a white paper by the mysterious Satoshi Nakamoto, whose true identity has yet to be verified. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government-issued currencies.

Mining is a record-keeping service done through the use of computer processing power.[e] Miners keep the blockchain consistent, complete, and unalterable by repeatedly grouping newly broadcast transactions into a block, which is then broadcast to the network and verified by recipient nodes.[64] Each block contains a SHA-256 cryptographic hash of the previous block,[64] thus linking it to the previous block and giving the blockchain its name.[3]:ch. 7[64]
Full clients verify transactions directly by downloading a full copy of the blockchain (over 150 GB As of January 2018).[90] They are the most secure and reliable way of using the network, as trust in external parties is not required. Full clients check the validity of mined blocks, preventing them from transacting on a chain that breaks or alters network rules.[91] Because of its size and complexity, downloading and verifying the entire blockchain is not suitable for all computing devices.

On 12 March 2013, a bitcoin miner running version 0.8.0 of the bitcoin software created a large block that was considered invalid in version 0.7 (due to an undiscovered inconsistency between the two versions). This created a split or "fork" in the blockchain since computers with the recent version of the software accepted the invalid block and continued to build on the diverging chain, whereas older versions of the software rejected it and continued extending the blockchain without the offending block. This split resulted in two separate transaction logs being formed without clear consensus, which allowed for the same funds to be spent differently on each chain. In response, the Mt. Gox exchange temporarily halted bitcoin deposits.[172] The exchange rate fell 23% to $37 on the Mt. Gox exchange but rose most of the way back to its prior level of $48.[56][57]

Though transaction fees are optional, miners can choose which transactions to process and prioritize those that pay higher fees.[67] Miners may choose transactions based on the fee paid relative to their storage size, not the absolute amount of money paid as a fee. These fees are generally measured in satoshis per byte (sat/b). The size of transactions is dependent on the number of inputs used to create the transaction, and the number of outputs.[3]:ch. 8


In 2013 and 2014, the European Banking Authority[144] and the Financial Industry Regulatory Authority (FINRA), a United States self-regulatory organization,[145] warned that investing in bitcoins carries significant risks. Forbes named bitcoin the best investment of 2013.[146] In 2014, Bloomberg named bitcoin one of its worst investments of the year.[147] In 2015, bitcoin topped Bloomberg's currency tables.[148]
Regulatory Risk: Bitcoins are a rival to government currency and may be used for black market transactions, money laundering, illegal activities or tax evasion. As a result, governments may seek to regulate, restrict or ban the use and sale of bitcoins, and some already have. Others are coming up with various rules. For example, in 2015, the New York State Department of Financial Services finalized regulations that would require companies dealing with the buy, sell, transfer or storage of bitcoins to record the identity of customers, have a compliance officer and maintain capital reserves. The transactions worth $10,000 or more will have to be recorded and reported.
Bitcoin is pseudonymous, meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" (e.g., transactions that spend coins from multiple inputs indicate that the inputs may have a common owner) and corroborating public transaction data with known information on owners of certain addresses.[111] Additionally, bitcoin exchanges, where bitcoins are traded for traditional currencies, may be required by law to collect personal information.[112]
Bitcoin's journey continued slowly at first, but it hit the mainstream in 2013 after the first of several hyperinflation incidents occurred in the currency. In late 2013, the cryptocurrency spike in value from around $100 per coin to $1,000 in just over a month, before halving in value over the next three or four months. Bitcoin would not hit $1,000 again until 2017.
That crash was made up for by a rally in October and November of that year. By early October, Bitcoin was at about $100, and it hit $195 by the end of the month. In November alone, Bitcoin had an unbelievable rally, going from $200 to more than $1,120. The causes of this rally were fairly obvious to most people, as more miners and exchanges were supporting Bitcoin. In addition, China had entered the marketplace.
The unit of account of the bitcoin system is a bitcoin. Ticker symbols used to represent bitcoin are BTC[b] and XBT.[c] Its Unicode character is ₿.[72]:2 Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), and satoshi (sat). Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoins, one hundred millionth of a bitcoin.[2] A millibitcoin equals 0.001 bitcoins, one thousandth of a bitcoin or 100,000 satoshis.[73]
Volatility. This very reason many speculators are attracted to Bitcoin is the same reason many potential users are hesitant to get involved. Users that look at Bitcoin as a speculative investment option are essentially gambling on the process, and the future price of Bitcoin is largely unknown. There are estimates that Bitcoin will both be worth pennies in a few years, while some predict that a single bitcoin will be worth $500k in three years. As new investors continue to invest and the market cap grows, Bitcoin’s price could become more stable. 

One of Bitcoin’s most appealing features is its ruthless verification process, which greatly minimizes the risk of fraud. Since Bitcoin is decentralized, volunteers—referred to as “miners”—constantly verify and update the blockchain. Once a specific amount of transactions are verified, another block is added to the blockchain and business continues per usual.
Press Contacts: San Francisco, CA, Kerryn Lloyd, [email protected] San Francisco, CA – August 28, 2018 –The Bitcoin Foundation has received a commitment of $200,000 for its 2018/2019 plan - $100,000 from Brock Pierce, a venture capitalist, philanthropist, serial entrepreneur and Chairman of the Bitcoin Foundation and a further $100,000 commitment [...]
“So if you look at a $100 billion market cap today, now last week it might have been more like 200, so it’s actually a buying opportunity, we think that there’s a potential appreciation of 30 to 40 times because you look at the gold market today, it’s a $7 trillion market. And so a lot of people are starting to se that, they recognize the store of value properties.”
In January 2014, Zynga[92] announced it was testing bitcoin for purchasing in-game assets in seven of its games. That same month, The D Las Vegas Casino Hotel and Golden Gate Hotel & Casino properties in downtown Las Vegas announced they would also begin accepting bitcoin, according to an article by USA Today. The article also stated the currency would be accepted in five locations, including the front desk and certain restaurants.[93] The network rate exceeded 10 petahash/sec.[94] TigerDirect[95] and Overstock.com[96] started accepting bitcoin.

Third-party internet services called online wallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware.[93][94] As a result, the user must have complete trust in the wallet provider. A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen. An example of such a security breach occurred with Mt. Gox in 2011.[95] This has led to the often-repeated meme "Not your keys, not your bitcoin".[96]
The other reason is safety. Looking at 2009 alone, 32,489 blocks were mined; at the then-reward rate of 50 BTC per block, the total payout in 2009 was 1,624,500 BTC, which at today’s prices is over $900 million. One may conclude that only Satoshi and perhaps a few other people were mining through 2009, and that they possess a majority of that $900 million worth of BTC. Someone in possession of that much BTC could become a target of criminals, especially since bitcoins are less like stocks and more like cash, where the private keys needed to authorize spending could be printed out and literally kept under a mattress. While it's likely the inventor of Bitcoin would take precautions to make any extortion-induced transfers traceable, remaining anonymous is a good way for Satoshi to limit exposure.
On 3 March 2014, Flexcoin announced it was closing its doors because of a hack attack that took place the day before.[211][212][213] In a statement that once occupied their homepage, they announced on 3 March 2014 that "As Flexcoin does not have the resources, assets, or otherwise to come back from this loss [the hack], we are closing our doors immediately."[214] Users can no longer log into the site.

Nobody owns the Bitcoin network much like no one owns the technology behind email or the Internet. Bitcoin transactions are verified by Bitcoin miners which has an entire industry and Bitcoin cloud mining options. While developers are improving the software they cannot force a change in the Bitcoin protocol because all users are free to choose what software and version they use.
In case you haven't read any of my Bitcoin Value Indicator reports, you can get caught up here. The idea is that since Bitcoin is a log scale phenomenon, and the organic growth of the network can be modeled using several proxies, then we can estimate a range of values that may be appropriate by using this data and creating meaningful visualizations with it.
Bitcoin mining saps energy, costly, uses more power and also the reward delays. For mining, run software, get your wallet ready and be the first to solve a cryptographic problem and you get your reward after the new blocks have been added to the blockchain.Mining is said to be successful when all the transactions are recorded in the blockchain and the new blocks are added to the blockchain.

In December 2013, Overstock.com[87] announced plans to accept bitcoin in the second half of 2014. On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins.[88] After the announcement, the value of bitcoins dropped,[89] and Baidu no longer accepted bitcoins for certain services.[90] Buying real-world goods with any virtual currency had been illegal in China since at least 2009.[91]
Bitcoin has become more widely traded as of 2017, and both short term traders and long-term investors are looking to participate in this exciting market. The price of bitcoin fluctuates on a daily basis, and can see some significant price volatility. Prices can be affected by numerous influences. Some of the possible drivers of price include: further acceptance, more exchanges opening, regulations, weakening paper currency values, inflation and more.
Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by trading it. The price of bitcoin skyrocketed into the thousands in 2017.
