Bitcoin is a virtual currency controlled by a decentralized user network that is not directly subjected to the national or central banking authorities’ whims. While hundreds of cryptocurrencies are currently in active use, Bitcoin is the most popular and widely used cryptocurrency – the closest of traditional government-mined currencies.
Bitcoin is worth about other currencies and physical goods, like traditional currencies, like the US dollar. Whole Bitcoin units can be divided into decimal places that represent smaller value units. The satoshi, or 0.00000001 Bitcoin, is currently the smallest bitcoin unit. The satoshi cannot be divided into tinier units. However, the source code of Bitcoin is structured so that subdivisions beyond this level can be allowed if the value of the currency is so appreciated as to be required.
Bitcoin is the most versatile of all. They can be utilized to acquire products from a growing roster of merchants (including well-known companies such as Expedia and Overstock.com). It can be exchanged for services or to settle outstanding debts with other private users. In electronic exchanges, which are similar to forex exchanges, it can be swapped for other currencies – both traditional and virtual. And unfortunately, it can also be used to facilitate illegal activities such as the purchase of dark websites of illicit drugs, such as the infamous Silk Road (and now shut down).

The Bitcoin source code includes intense privacy protection. This system allows Bitcoin and other relevant data to be recorded publicly without revealing the person’s or groups’ identity. Instead, Bitcoin users are identified through public keys or numeric codes, sometimes pseudonymous handles or user names.
Further protection permits users to disguise the Bitcoin source and flow further. For instance, all Bitcoin users have unique computer systems known as mixing services, swap a particular Bitcoin unit privately for a different Bitcoin device with equal value, thus obscuring the source of the owner’s holdings.
Exchanges of Bitcoin
Bitcoin exchanges offer users the opportunity to exchange Bitcoin units at variable exchange rates for fiat currencies, such as US dollars and euro. Many Bitcoin exchanges also change Bitcoin units for other cryptocurrencies, including the least popular options, for which fiat currencies cannot be directly exchanged. In most Bitcoin exchanges, the value of each transaction is cut, typically less than 1 percent.
Bitcoin exchanges ensure that Bitcoin remains liquid, fixing its value relative to traditional currencies and making it possible for holders to take advantage of speculation about fluctuations in that value. That said, Bitcoin users must realize that the value of Bitcoin is subject to wild swings – 50 percent weekly movements have occurred in either direction previously. These changes in stable fiat currencies are unpredictable.
For its function, Bitcoin’s blockchain is vital. The blockchain is a public, distributed directory of all Bitcoin previous transactions stored in groups known as blocks. The Bitcoin blockchain contains an equal record for each node of Bitcoin’s software network — server farms and terminals operated by people or classes known as ‘miners’ whose work to create new Bitcoin units results in Bitcoin’s recording, authentication, and periodic build-up of new blocks.
Since new Bitcoin transactions occur constantly, the Bitcoin blockchain grows over time, though finite. Until miners continue working and record recent transactions, the Bitcoin blockchain always works. In other words, the blockchain will no longer grow at a predetermined length.
On average, Miners create a new blockchain every 10 minutes, including all previous transactions and a new transaction block. Bitcoin’s source code is designed every two weeks to adapt to the amount of mining power used to create new blockchains, maintaining the average creation interval of ten minutes. When mining power increases over the last two weeks, it becomes harder to create new blockchains over the next two weeks. By decreasing mining power, it is easier to generate new chains. The trend has been towards greater mining power for most of Bitcoin’s history.
At least one private key (essentially a password) is available for every Bitcoin user, a real number between 1 to 78 digits. Single users can have several anonymous handles, each with their private key. Users cannot complete transactions without them accessing their holdings until the corresponding key is recovered.
Users create their private keys manually or use the same number generator. Private keys confirm the identity of their owners and allow Bitcoin to be used or received. Key stores can be stored online, on the physical storage media (e.g., thumb drives, on paper or in the private Cloud or on public Bitcoin interchanges), and only online in transactions.
Given the importance of personal keys to Bitcoin holdings, security experts advise against the easy-to-reach storage of private keys or keep just one private copy of them. On paper printouts and non-internet-connected physical media, Savvy users store identical key copies.
