Bitcoin is often called the first cryptocurrency[18][19][20] although prior systems existed.[note 8] Bitcoin is more accurately referred to as the very first decentralized digital money.[13][23]
Among the primary supporters, adopters, contributor to bitcoin and receiver of the first bitcoin transaction was programmer Hal Finney. Finney downloaded the bitcoin software the day it was released, and received 10 bitcoins in the first bitcoin trade of the world's from Nakamoto.[77][78]
Other early supporters were Wei Dai, originator of bitcoin forerunner b-cash, originator of bitcoin forerunner bit gold and Nick Szabo,.[79]
In 2010, an exploit within an early bitcoin client was discovered that allowed large numbers of bitcoins to be created.[80] The artificially created bitcoins were removed when another chain overtook the bad chain.
Bitcoins are created as a reward for payment processing work by which users offer their computing power record and to verify payments to the public ledger. This activity is called mining and is rewarded by transaction fees and just created bitcoins.[14] Besides mining, bitcoins can be obtained in exchange for fiat money, goods, and services.[25] Users can send and receive bitcoins for a discretionary trade fee.[26]
Bitcoin as a kind of payment for products and services has grown,[25] and merchants have an incentive to take it because fees are lower in relation to the 2-3% typically demanded by credit card processors.[27] This is due to two things; in Bitcoin the fees are magnitudes lower,[28] and unlike bank cards, the small fees there are are paid by the purchaser, not the vendor. The European Banking Authority[29] and other sources[14]:11 have warned that refund rights or chargebacks not protect bitcoin users.
The use of bitcoin by criminals has attracted the interest of financial regulators,[30] legislative bodies,[31] law enforcement,[32] and media.[33] They listed money laundering, financing of illegal actions, larceny, fraud, tax evasion, and use in black markets as you possibly can. As of 2013, the criminal actions centered around theft and black markets. Officials in countries such as the United States also recognized that bitcoin can provide customers with valid financial services.
