Bitcoin is an increasingly popular cryptocurrency that utilizes blockchain technology to facilitate transactions. Basically, a user obtains a Bitcoin wallet that can be used for storing bitcoins and both sending and receiving of payments. The blockchain technology used by Bitcoin is really just a shared public ledger that is used by the entire public network. The technology used is secured through cryptography, a branch of mathematics that provides a highly secure means of facilitating and recording transactions on the network.
Although there are no guarantees that Bitcoin will continue to rise in value, the future does look bright for this exciting cryptocurrency. Unlike leveraged instruments, you can rest assured that your exposure to Bitcoin is limited to what you pay for it. (This does not apply to Bitcoin or other cryptocurrency derivatives that may be leveraged or shorted).
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]
Meanwhile, investors have been rattled this week by reports bank-owned currency trading utility CLS, along with enterprise software giant IBM, are teaming up to trial the blockchain-based Ledger Connect, an application that offers services from different vendors, with some nine financial institutions, including international heavyweights Barclays and Citigroup.
Satoshi's anonymity often raises unjustified concerns because of a misunderstanding of Bitcoin's open-source nature. Everyone has access to all of the source code all of the time and any developer can review or modify the software code. As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper.

"While crypto markets have seen rapid growth, such trading platforms don’t seem to be well-enough prepared in terms of security," said Hong Seong-ki, head of the country's cryptocurrency response team South Services Commission. "We’re trying to legislate the most urgent and important things first, aiming for money-laundering prevention and investor protection. The bill should be passed as soon as possible."


According to The New York Times, libertarians and anarchists were attracted to the idea. Early bitcoin supporter Roger Ver said: "At first, almost everyone who got involved did so for philosophical reasons. We saw bitcoin as a great idea, as a way to separate money from the state."[119] The Economist describes bitcoin as "a techno-anarchist project to create an online version of cash, a way for people to transact without the possibility of interference from malicious governments or banks".[122]
This is a rather simple long term model.  And perhaps the biggest question it hinges on is how much adoption will bitcoin achieve?  Coming up with a value for the current price of bitcoin would involve pricing in the risk of low adoption or failure of bitcoin as a currency, which could include being displaced by one or more other digital currencies.  Models often consider the velocity of money, frequently arguing that since bitcoin can support transfers that take less than an hour, the velocity of money in the future bitcoin ecosystem will be higher than the current average velocity of money.  Another view on this though would be that velocity of money is not restricted by today's payment rails in any significant way and that its main determinant is the need or willingness of people to transact.  Therefore, the projected velocity of money could be treated as roughly equal to its current value.

Bitcoin’s popularity has undeniably been its number one advantage over the numerous other cryptocurrencies. By gaining a large number of adopters and users, Bitcoin has achieved a network effect that attracts even more users. Users who would otherwise be more apprehensive investing in a relatively unknown and unproven digital currency are reassured by Bitcoin’s performance over time, its growing community, and the fact that people they know are adopting cryptos.
M3 (which includes all the other buckets) minus M1 is worth about 45 trillion US dollars.  We will include this as a store of value that is comparable to bitcoin.  To this, we will also add an estimate for the worldwide value of gold held as a store of value.  While some may use jewelry as a store of value, for our model we will only consider gold bullion.  The US Geological Survey estimated that at the end of 1999, there were about 122,000 metric tons of available above-ground gold.  Of this, 48%, or 58,560 metric tons, was in the form of private and official bullion stocks.  At an estimated current price of $1200 per troy ounce, that amount of gold is today worth upwards of 2.1 trillion US dollars.  Since there has recently been a deficit in the supply of silver and governments have been selling significant amounts of their silver bullion, we reason that most silver is being used in industry and not as a store of value, and will not include silver in our model.  Neither will we treat other precious metals or gemstones.  In aggregate, our estimate for the global value of stores of value comparable to bitcoin, including savings accounts, small and large time deposits, money market funds, and gold bullion, come to 47.1 trillion US dollars.

On 6 August 2010, a major vulnerability in the bitcoin protocol was spotted. Transactions weren't properly verified before they were included in the transaction log or blockchain, which let users bypass bitcoin's economic restrictions and create an indefinite number of bitcoins.[25][26] On 15 August, the vulnerability was exploited; over 184 billion bitcoins were generated in a transaction, and sent to two addresses on the network. Within hours, the transaction was spotted and erased from the transaction log after the bug was fixed and the network forked to an updated version of the bitcoin protocol.[27] This was the only major security flaw found and exploited in bitcoin's history.[25][26]
It would seem even early collaborators on the project don’t have verifiable proof of Satoshi’s identity. To reveal conclusively who Satoshi Nakamoto is, a definitive link would need to be made between his/her activity with Bitcoin and his/her identity. That could come in the form of linking the party behind the domain registration of bitcoin.org, email and forum accounts used by Satoshi Nakamoto, or ownership of some portion of the earliest mined bitcoins.  Even though the bitcoins Satoshi likely possesses are traceable on the blockchain, it seems he/she has yet to cash them out in a way that reveals his/her identity. If Satoshi were to move his/her bitcoins to an exchange today, this might attract attention, but it seems unlikely that a well-funded and successful exchange would betray a customer's privacy.
A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold[87] or store bitcoins,[88] due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A better way to describe a wallet is something that "stores the digital credentials for your bitcoin holdings"[88] and allows one to access (and spend) them. Bitcoin uses public-key cryptography, in which two cryptographic keys, one public and one private, are generated.[89] At its most basic, a wallet is a collection of these keys.
As the first cryptocurrency, Bitcoin’s long price history should come as no surprise. Bitcoin was created in 2009 by Satoshi Nakamoto, an alias for a person or group who has still not been revealed. Over the years, it has hit many highs and lows, To better understand the past of this cryptocurrency, as well as its potential in the future, take a deeper delve into its history.
