Bitcoin is a virtual currency, or cryptocurrency, that’bitcoin art shop controlled by a decentralized network of users and isn’t directly subject to the whims of central banking authorities or national governments. Like traditional currencies, such as the U.
Bitcoin has value relative to other currencies and physical goods. Whole Bitcoin units can be subdivided into decimals representing smaller units of value. Currently, the smallest Bitcoin unit is the satoshi, or 0. The satoshi can’t be broken into smaller units. Bitcoin is the most versatile cryptocurrency. It can be exchanged with other private users as consideration for services performed or to settle outstanding debts. It can be swapped for other currencies, both traditional and virtual, on electronic exchanges that function similar to forex exchanges.
For all its promise, Bitcoin remains a niche currency that’s subject to wild value fluctuations. Despite the wild-eyed pronouncements of hardcore proponents, it’s certainly not a legitimate investment or trading vehicle, as is the case with stable national currencies, such as the U. How Bitcoin Works Bitcoin is a cryptocurrency, meaning it’s supported by a source code that uses highly complex algorithms to prevent unauthorized duplication or creation of Bitcoin units. The code’s underlying principles, known as cryptography, are based on advanced mathematical and computer engineering principles. It’s virtually impossible to break Bitcoin’s source code and manipulate the currency’s supply.
User Anonymity Intense privacy protections are baked into Bitcoin’s source code. The system is designed to publicly record Bitcoin transactions and other relevant data without revealing the identity of the individuals or groups involved. Instead, Bitcoin users are identified by public keys, or numerical codes that identify them to other users, and sometimes pseudonymous handles or usernames. Additional protections allow users to further conceal the source and flow of Bitcoin. Bitcoin Exchanges Bitcoin exchanges allow users to exchange Bitcoin units for fiat currencies, such as the U. Many Bitcoin exchanges also exchange Bitcoin units for other cryptocurrencies, including less popular alternatives that can’t directly be exchanged for fiat currencies.
Block Chain Bitcoin’s block chain is vital to its function. The block chain is a public, distributed ledger of all prior Bitcoin transactions, which are stored in groups known as blocks. 1 and 78 digits in length. Individual users can have multiple anonymous handles, each with its own private key. Private keys confirm their owners’ identities and allow them to spend or receive Bitcoin. Miners Miners play a vital role in the Bitcoin ecosystem. As keepers of the block chain, they keep the entire Bitcoin community honest and indirectly support the currency’s value.
They perform incredibly complex mathematical tasks in an effort to mint new Bitcoin, which they then keep or exchange for fiat currency. Finite Supply Bitcoin’s own source code places a strict limit on the number of Bitcoin units that can ever exist: 21 million. This is achieved by slowing, over time, the rate at which the creation of new block chain copies produces new Bitcoin. Every four years or so, this rate halves.
Risk of Theft Taken together, the security risks around Bitcoin are the currency’s single greatest drawback, and are worthy of special consideration for anyone considering converting U. The fact that Bitcoin units are virtually impossible to duplicate does not mean that Bitcoin users are immune to theft or fraud. Common Modes of Bitcoin Theft It usually takes more technical skill to steal Bitcoin than physical cash. Most Bitcoin heists involve sophisticated hack attacks by highly accomplished outsiders or rogue exchange employees. Private keys stored in publicly accessible digital repositories, such as Bitcoin exchanges or personal cloud storage drives, are vulnerable to theft by hacking.
