Bitcoin is a payment system invented by Satoshi Nakamoto, who published the invention in 2008 and released it as open-source software in 2009. The system is peer-to-peer; users can transact directly without needing an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the block chain. The ledger uses its own unit of account, also called bitcoin. The system works without a central repository or single administrator, which has led the US Treasury to categorize it as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value.
Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into the public ledger. This activity is called mining and the miners are rewarded with transaction fees and newly created bitcoins. Besides mining, bitcoins can be obtained in exchange for different currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.
Bitcoin as a form of payment for products and services has grown, and merchants have an incentive to accept it because fees are lower than the 2–3% typically imposed by credit card processors. Unlike credit cards, any fees are paid by the purchaser, not the vendor. The European Banking Authority and other sources have warned that bitcoin users are not protected by refund rights or chargebacks. Despite a big increase in the number of merchants accepting bitcoin, the cryptocurrency doesn’t have much momentum in retail transactions.
The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and media. Criminal activities are primarily centered around black markets and theft, though officials in countries such as the United States also recognize that bitcoin can provide legitimate financial services.
A T-shirt (or tee-shirt, or tee) is a style of fabric shirt, named after the T shape of the body and sleeves. It is normally associated with short sleeves, a round neck line known as a crew neck, and no collar.
Typically made of cotton fibers knitted in a jersey stitch, they have a distinctive soft texture compared to woven shirts. The majority of modern versions have a body made from a continuously woven tube, on a circular loom, so that the torso has no side seams. The manufacture of T-shirts has become highly automated, and may include fabric cutting by laser or water jet.
The T-shirt evolved from undergarments used in the 19th century, through cutting the one-piece union suit underwear into separate top and bottom garments, with the top long enough to tuck under the waistband of the bottoms. With and without buttons, they were adopted by miners and stevedores during the late 19th century as a convenient covering for hot environments.
As slip-on garments without buttons, they originally became popular in the United States when they were issued by the U.S. Navy during or following the Spanish–American War of 1898. These were a crew-necked, short-sleeved, white cotton undershirt to be worn under a uniform. It became common for sailors and Marines in work parties, the early submarines, and tropical climates to remove their uniform jacket, wearing (and soiling) only the undershirt.
They soon became popular as a bottom layer of clothing for workers in various industries, including agriculture. The T-shirt was easily fitted, easily cleaned, and inexpensive, and for those reasons it became the shirt of choice for young boys. Boys’ shirts were made in various colors and patterns. By the Great Depression, the T-shirt was often the default garment to be worn when doing farm or ranch chores, as well as other times when modesty called for a torso covering but conditions called for lightweight fabrics.
A V-neck T-shirt has a V-shaped neckline, as opposed to the round neckline of the more common crew neck shirt. V-necks were introduced so that the neckline of the shirt does not stand out when an outer shirt is worn over it, thus reducing or eliminating the visible cloth above the outer shirt of a crew neck shirt.
