tual currency created on the Internet in 2009, bitcoin knows strong shaking. After flailing last week, he earned $ 1,000 Monday. Without reason! This rise, which nothing explains, does not prevent the currency from seducing more and more investors.

Bitcoin was created on the Internet in 2009 by a mysterious group of computer programmers who used the name Satoshi Nakamoto as a pseudonym. This virtual currency, which can occasionally pay for the Internet or in some cafes, for example, has a specific price, set by the game of supply and demand. It is based on a few simple principles: anonymity of transactions, decentralization of currency control, convertibility into dollars and euros essentially.

The system is based on a decentralized architecture. Individuals are invited to become the nodes of this system. By connecting their personal computers to the network, they participate by solving mathematical equations in the creation of the currency. They become in the language of bitcoin, "minors". However, only experienced computer scientists can embark on the adventure of "mine" and money creation. And they are more numerous. Bitcoin "mining" farms are proliferating all over the planet. Which is energy-consuming. It is considered that the system consumes as much electricity as Nigeria.
