Bitcoin (abbreviation: BTC or XBT; sign: ₿) is the first decentralized cryptocurrency.

Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight.

Consensus between nodes is achieved using a computationally intensive process based on proof-of-work, called mining, that requires increasing quantities of electricity and guarantees the security of the bitcoin blockchain.

A cryptocurrency exchange, or a digital currency exchange (DCE), is a business that allows customers to trade cryptocurrencies or digital currencies for other assets, such as conventional fiat money or other digital currencies.

Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for digital currencies or cryptocurrencies.

A cryptocurrency exchange can be a market maker that typically takes the bid–ask spreads as a transaction commission for its service or, as a matching platform, simply charges fees.

A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.

In trade, barter (derived from baretor) is a system of exchange in which participants in a transaction directly exchange goods or services for other goods or services without using a medium of exchange, such as money.

Economists usually distinguish barter from gift economies in many ways; barter, for example, features immediate reciprocal exchange, not one delayed in time.

Barter usually takes place on a bilateral basis, but may be multilateral (if it is mediated through a trade exchange).

In most developed countries, barter usually exists parallel to monetary systems only to a very limited extent.

Market actors use barter as a replacement for money as the method of exchange in times of monetary crisis, such as when currency becomes unstable (such as hyperinflation or a deflationary spiral) or simply unavailable for conducting commerce.

Using resources, skill, ingenuity, and experience, service provider's benefit service consumers.

Services may be defined as intangible acts or performances whereby the service provider provides value to the customer.
