How we work

Bitcoin is a cryptocurrency, which is a form of electronic cash. This is the first decentralized digital currency: the system was designed to work without a central bank or a single administrator. Many economists and investors consider the Bitcoin market to be a bubble. Bitcoin has also been criticized for its use in illegal transactions, its high power consumption, price instability, and theft from exchanges.

What Is Real Cryptocurrency
Bitcoin is made as a reward for the process known as mining. They can be exchanged for other currencies, products and services. The research produced by Cambridge University estimates that in 2017, there were 2.9 to 5.8 million unique users using cryptocurancency wallet, most of which used bittoine. A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.

Bitcoin, created in 2009, was the first decentralized cryptocurrency. Since then, numerous cryptocurrencies have been created. These are frequently called altcoins, as a blend of bitcoin alternative. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/central banking systems . The decentralized control is related to the use of bitcoin's blockchain transaction database in the role of a distributed ledger
