What is Bitcoin?
Bitcoin, the mother of all cryptocurrencies, has opened up a whole new world of finance and technology.

Bitcoin defies logic, challenges convention and since its invention in 2008 has opened the door to a new wave of innovation in finance and technology.
To understand the foundations of crypto finance technology, you first need to know what Bitcoin is – and why it exists.
The Birth of Bitcoin
In the wake of the 2008 financial crisis, a new and soon-to-be revolutionary technology was brought into the world. Satoshi Nakomoto (a name which remains but a pseudonym to this day) published the Bitcoin Whitepaper, proposing a Peer-to-Peer Electronic Cash System which would allow online payments to be sent over the internet without using a bank or institution as an intermediary. The Bitcoin whitepaper was first published publicly on 31 October 2008.
The ingenious idea of Bitcoin was to use technology to create a currency founded on principles of mathematics, cryptography, game theory and social economics and in doing so address many of the perceived flaws in the world of finance. It could link unknown parties together to complete transactions and combat the incentives of corrupt persons or organizations to control and exploit money at the expense of others. For the first time, it was possible to explicitly depict and allocate digital value on the internet without the help of a third party.
Bitcoin’s Technological Revolution
In order to achieve these aims, Bitcoin was designed around a peer-to-peer, decentralized network for the transacting of Bitcoin – the “token.”
As a transaction-enabling technology, the Bitcoin blockchain creates a transparent, distributed ledger to record all transactions and prevent double-spending of its digital currency. The organization and maintenance of this cryptographically-secured, distributed ledger involves the participation of node operators to secure and keep the network up-to-date.
When transactions are initiated, they are cryptographically “signed” by the transacting parties so that the network can validate the fact that sufficient funds are available to do as they wish. Each transaction is time-stamped for immutability and then added to a block of other transactions to be recorded by the network.
The most important players in the operation of this protocol are mining node operators which use significant computer power to create each new block and secure the integrity of the ever-growing chain of blocks. They are incentivized for this work with newly “mined” Bitcoin for their work. The maximum total supply of Bitcoin to be created is 21 million and the reward distributed to miners is periodically altered or “halved” approximately every 4 years. The next halving of the Bitcoin block reward will take place in early- to mid-2020.
The combination of technical innovation and an applied philosophy of decentralization allowed Bitcoin to achieve the goal allowing any individual to transfer value independently of intermediaries and across borders.
Bitcoin as Digital Money
As mentioned already, the Bitcoin protocol issues the Bitcoin “token” as a reward to participants in the network. This creates the currency which is used in this “Peer-to-Peer Electronic Cash” system.
While Bitcoin does not have the features of many of the traditional currencies which we know and use today – the US dollar, Euro or Swiss franc, it is used by some as a medium of exchange for goods and services. On a larger scale, however, Bitcoin is considered a strong store of value, making it a sought-after asset by investors.
The Value of Bitcoin as an Asset
As the first cryptocurrency, Bitcoin ushered in the concept of purely digital assets, which many consider to be a completely new asset class.
Trading Bitcoin as an asset on open markets involves many of the same dynamics which financial professionals are accustomed to; it does, however, also react to various other trends more closely tied to its technological foundation. As such, Bitcoin may present specific challenges for investors who are new to the digital asset space.
Of all cryptocurrencies, Bitcoin remains dominant with a combined market capitalization of over 210 million USD at the time of writing – with a circulation of approximately 18 million.
Bitcoin is traded across a wide range of marketplaces and exchanges. Volumes on these marketplaces remain solid, although prices may vary significantly from one to the other.
Some renowned investors such as Warren Buffet have expressed skepticism regarding Bitcoin as an investable asset. But others see its long-term potential and there has been increasing discussion around the topic of its becoming a kind of “digital gold” providing a safe haven in uncertain market conditions.
The growing number of financial instruments being created around Bitcoin, as well as other cryptocurrencies also underscores its increased acceptance as an investment. Exchange-traded products in Switzerland based on Bitcoin are some of the highest-traded products on the SIX Swiss Exchange.
Conclusion
Bitcoin is here to stay. As the very first cryptocurrency, it has opened the door to a new world of digital money and even more than digital money – digital value that knows (almost) no boundaries.
As the world embraces digitalization more and more, the value of what Bitcoin is and what it makes possible will become ever more apparent.

For instance, the ancient Egyptians, whose numeral system lacked a zero, had an extremely cumbersome way of handling fractions: instead of thinking of 3/4 as a ratio of three to four (as we do today), they saw it as the sum of 1/2 and 1/4. The vast majority of Egyptian fractions were written as a sum of numbers as 1/n, where n is the counting number—these were called unit fractions. Without zero, long chains of unit fractions were necessary to handle larger and more complicated ratios (many of us remember the pain of converting fractions from our school days). With zero, we can easily convert fractions to decimal form (like 1/2 to 0.5), which obsoletes the need for complicated conversions when dealing with fractions. This is the 'unit of account' function of zero. Prices expressed in money are just exchange ratios converted into a money-denominated price decimal: instead of saying 'this house costs eleven cars' we say, 'this house costs $440,000,' which is equal to the price of eleven $40,000 cars. Money gives us the ability to better handle exchange ratios in the same way zero gives us the ability to better handle numeric ratios.cryptocurrency это суть bitcoin zona bitcoin electrodynamic tether drip bitcoin
proxy bitcoin For context, at 90 exahashes per second, the bitcoin network currently consumes approximately 9 gigawatts of power, which translates to -$11 million per day (or -$4 billion per year) of energy at a marginal cost of 5 cents per kWh (rough estimates). Blocks are solved on average every ten minutes, which translates to approximately 144 blocks per day. Across the network, each block costs approximately $75,000 to solve, and the reward per block is approximately $100,000 (12.5 new bitcoin x $8,000 per bitcoin, excluding transaction fees). The higher the cost to solve a block, the more costly the network is to attack. The cost to solve a block represents the tangible resources it requires to write history to the bitcoin transaction ledger. As the network grows, the network becomes more fragmented, and the economic value compensated to miners in aggregate increases. From a game theory perspective, more competition and greater opportunity cost makes it harder to collude, and all network nodes validate the work performed by miners, which serves as a constant check and balance.ecopayz bitcoin my ethereum monero пул half bitcoin книга bitcoin bitcoin торги

ферма bitcoin decred ethereum Other real-time gross settlement systems, such as the FedWire system operated by the Federal Reserve, transacting in Federal Reserve Notes, can be used as a basis for comparison (in terms of overhead costs, security, and flexibility) to the Bitcoin system, which uses bitcoins as the store of value, unit of account, and medium of exchange. Without the prospect of the improvement of the protocol, as compared to banking equivalents, there is little prospect of increasing the price of Bitcoin; in turn, a stagnant price reduces financial incentive for selfish individuals to keep contributing code and advancing the system.ethereum курс bitcoin принцип keystore ethereum биржи bitcoin dwarfpool monero bitcoin вектор ethereum farm лотереи bitcoin surf bitcoin bitcoin аккаунт ethereum настройка tether bitcointalk торги bitcoin service bitcoin visa bitcoin платформы ethereum проекты bitcoin ethereum github bitcoin зарегистрироваться bitcoin london логотип bitcoin sell ethereum algorithm bitcoin bitcoin 9000 кошельки bitcoin metropolis ethereum ethereum контракт bitcoin synchronization bitcoin cache bitcoin darkcoin
