Jump to: , By far the most commonly used symbol for Bitcoin is , a capital letter B with two vertical lines "going through" it, though the lines are only visible at the top and bottom.This symbol was created by Satoshi Nakamoto for the icon of an early version of the original Bitcoin client, though the very first versions of the Bitcoin client used "BC" instead of any special symbol.Presumably the symbol was intended to look similar to other currency symbols.The symbol represents the currency unit "bitcoin" (100 million satoshi), as well as the Bitcoin network and currency itself.The bitcoin currency unit is also commonly given the informal currency code BTC.The Bitcoin sign is part of Unicode 10.0 (released June 2017)[1] with code point U+20BF (₿).As of June 2017, font support for the Bitcoin sign is in macOS Sierra, iOS, Android O beta, Windows 10 Creators Update and several Linux releases.The Bitcoin sign was accepted for Unicode in November 2015[2] and completed the Unicode process in 2017.

Historically, similar looking Unicode symbols such as the Thai Baht (฿) have been used because the Unicode standard at the time had not included a symbol for Bitcoin.Contents 1 2 3 The ISO 4217 currency code for Bitcoin is XBT.However, at the moment it is an unofficial code according to the ISO 4217 standard.The unit name BTC is also commonly used to represent one bitcoin, but it violates ISO 4217 because it begins with "BT", the country code of Bhutan.Bhutan does not actually use the code BTC for any currency, and XBT has not yet defined which unit it represents (just that it represents some unit of bitcoin), so the Bitcoin community is likely to continue using mainly BTC as a unit name and currency code for some time.A formal application by the Financial Standards Working Group of the Bitcoin Foundation is nearing completion [still true?].This application would request ISO 4217 standard to support XBT.In lieu of the Bitcoin symbol being included in the Unicode standard and its adoption into typographic fonts, BTC can be included in many documents by other means.

This section focuses on online publications but the basic concepts apply to all publishing forms.bitcoin 500ghA package including a high resolution raster image with transparency (PNG), vector image (SVG) and TrueType font (TTF) is available[3] The Bitcoin symbol can be inserted as an image, as is done in the opening sentence of this page.delete bitcoin walletThe benefit of this method is that any client that can display images in line with text will be able to display the symbol.bitcoin meetup argentinaThe down side to this method is that as an image, it does not always degrade as nicely as a font.own bitcoin forkIf using raster image, scaling the image up/down (to fit with surrounding text) may result in pixelation, inappropriate filtering, and other issues typical of raster images.bitcoin forum irc

If using a vector image, scaling concerns do not apply but the display would still not benefit from font-specific rendering features such as hinting.buy bitcoin redeemable codeBoth forms also suffer from client-specific considerations such as whether or not a box will be drawn around the image and the general inability to easily style its display; applying color requires specific CSS, and italicizing would require a CSS skew transform, for example.bitcoin for sale in ghanaWhen using an image in running text on a webpage it's generally a good idea to set the alt property to an appropriate value.bitcoin citizenshipFor example, when depicting amounts you might use alt="BTC".bitcoin aktueller preis

Text including the symbol copied and pasted will then remain syntactically correct, replacing the symbol with BTC.The Font Awesome collection of icons and symbols also includes the Bitcoin symbol.[4]As few fonts include the Bitcoin symbol, a special font was created by User:Theymos, originally for the BitcoinTalk forum[5].The font consists of only the Bitcoin symbol used in the glyph for the capital letter B.The text "BTC" can be entered and styled with this font, causing it to be replaced entirely with just the symbol on those systems that support this font, while on other systems the text "BTC" is retained.Similarly, copying and pasting text will still retain "BTC".This method is used on BitcoinTalk and this Bitcoin Wiki.A formal ISO currency code will spur global mainstream adoption of bitcoin more than any other single action.When a new currency code becomes adopted by the independent and nonpolitical International Organization for Standardization (ISO), it immediately enters the database tables upon which Visa, MasterCard, PayPal, SWIFT and other clearing networks rely.

ISO 4217 is a standard published by the ISO, which delineates currency designators, country codes (alpha and numeric) and references to minor units in three separate tables.Now, a distributed currency having an identifiable code in a centralized database may not seem like much of an accomplishment.However, when we consider what this means for integration into existing networks, trading systems and software accounting systems, it becomes much more significant.All the more so when we consider that a code prefix of 'X' denotes a non-national affiliation or a monetary metal such as gold or silver.Instantly, bitcoin as XBT will be available as a selectable clearing and settlement unit for any business that chooses to offer and implement bitcoin.Of course, designing and managing the necessary settlement and hedging mechanisms will be a different matter altogether.Certain clearing networks may effectively become bitcoin exchanges.With the three-character code having been in informal usage since early 2013, a formal application for XBT is nearing completion by the Financial Standards Working Group within the Bitcoin Foundation.

, the world's platform for change.The petition closed with 836 supporters.Since the decentralized bitcoin has a peer-to-peer block chain rather than an 'official' currency manager, a central bank or an existing institution such as SWIFT may also be necessary to support the ISO application for XBT.As leaders of financial innovation through their Innotribe initiative, early indications from SWIFT senior management are that they would be supportive of such an application, if required.Recently, the topic of XBT and the need to standardize various subunits has been much debated on Reddit and other social media outlets, unfortunately causing more confusion than clarification.Let's examine some of the top-level issues.The code XBT was selected because the prefix 'X' denotes a non-national affiliation or a monetary metal such as gold or silver.Technically, BTC would be unavailable due to the fact 'BT' already represents the country of Bhutan.The first two letters of the code are the two letters of the country code (as with national top-level domains on the Internet) and the third is the initial of the currency itself.

In the case of the dollar (USD), US represents the country and D represents the initial of the currency.Most likely, BTC would still remain in colloquial usage because it is already widely recognized by the community.Just as slang terms for money exist around the world, BTC shorthand would be used similar to how 'bucks' or 'quid' are used for other currencies.In this scenario, I expect BTC to continue to represent one full bitcoin unit.One XBT unit as listed and recorded within ISO 4217 would have eight subunits or decimal places to the right of the decimal point.The rationale for this is that a neutral global default for bitcoin around the world cannot deviate from the unit's representation on the block chain (as expressed in the reference implementation) and the bitcoin integer in the core protocol is not changing.One bitcoin on the block chain must equal one bitcoin in the formal standards world or else processing errors would be potentially catastrophic.Even though eight decimals was selected as the starting point for the bitcoin integer, that number may need to be increased over time and increasing the amount of decimal places for bitcoin would hardly be a contested issue by the miners when the time comes.

The code representation within ISO 4217 cannot be changed up and down due to the varying number of decimal places in the core protocol.It must remain static.Bitcoin is correctly placed, alongside gold, as a digital cryptographic commodity.So, just as gold (XAU) may trade in some areas as kilos or kilograms, the global default standard for pricing and measuring quantities of gold bullion remains the troy ounce.One troy ounce is currently defined as 31.1034768 grams and is equivalent to approximately 1.09714 avoirdupois ounces.XAU denotes one troy ounce of gold and 'XAU/USD' means the price of 1 troy ounce of gold in US dollars.Despite the fact that several names for bitcoin's minor units have been proposed, only three of the minor units, or subunits, have achieved a consensus within the bitcoin economy.The third space after the decimal point (10−3) is commonly referred to as 'millibit' or mBTC.The sixth space after the decimal point (10−6) is commonly referred to as 'bit' or μBTC.The eighth space after the decimal point (10−8) is commonly referred to as a 'satoshi', the smallest available amount of bitcoin today.

These existing minor units of bitcoin will be submitted in the ISO application for XBT and it is not required for all of the individual minor units to be submitted.To better facilitate consumer applications, some bitcoin operators may elect to provide a choice for display preferences.Several applications and web sites, such as BitcoinAverage, already permit toggling between bitcoin and millibit for display purposes.Recently, some exchange operators have also expressed an interest and willingness to display prices in bits, so that only two decimal places exist to the right of the integer.For instance, KnCMiner embraced the bits display option for its wallet app.These moves could be especially useful for accounting packages that typically accommodate only two decimal points.Strong opinions exist on all sides for going to a bits display, a millibits display, or remaining with a full bitcoin display.As a consensus emerges, it is also perceived as useful to utilize one expression for retail consumers and to maintain a full bitcoin expression for wholesale level or institutional trading.
