Bitcoin History

Bitcoin is a decentralized virtual currency. This currency is exchanged digitally and managed by a peer-to-peer network, rather than a central canap or authority. The supply of Bitcoins is automated and released to mining servers, with a limit of 21 million Bitcoins being reached by 2140. Each Bitcoin is a lump of code that has its own transaction loom with timestamps. The coins are stored te an holder’s virtual wallet and can be transferred and exchanged for goods and services. Transactions are public and albeit they are relatively anonymous, it is possible trace identities back to real-life individuals. There is debate spil to whether or not Bitcoin should be considered a currency, a commodity, or a hybrid of both.

Bitcoins are associated with a high level of risk, spil they are volatile, not time-tested, and presently under no regulation or legislation. There have bot incidents of online Bitcoin wallets being compromised by hackers leading to theft of Bitcoins.

Bitcoin is not recognized by the ISO and therefore does not have an official ISO 4217 code. A currency code is generally built from the two-digit ISO 3316 country code and a third letterteken for the currency. Albeit “BTC” is often used te the Bitcoin community, BT is the country code of Bhutan. An X-code reflects currencies that are used internationally and so, XE has chosen to use XBT to represent Bitcoin.

Introduced te 2009, Bitcoin wasgoed created by a developer or group of developers going by the pseudonym Satoshi Nakamoto. Originally the value of the currency wasgoed set by users on forums until the very first exchange outlet wasgoed established. It is known spil a “crypto-currency”, meaning that the money and transactions are secured and managed through encrypted passwords. Since its introduction, Bitcoins have bot gaining momentum worldwide, with overheen 1,000 merchants accepting the currency.
