Bitcoin ؟

Bitcoin is a legal currency and a global payment system comparable to other currencies such as the dollar or the euro

, but with several fundamental differences, most notably that it is a fully electronic currency that trades only online without a physicist. [1] it is the first decentralized digital currency - a system that operates without a central repository or a single manager, i.e., it differs from the traditional currencies in the absence of a central regulator behind it. Transactions are carried out in a peer-to-peer network between users directly, without intermediary, through the use of encryption. These transactions are verified through network nodes and recorded in a distributed and general ledger called block chain. Bitcoin was invented by an unknown person or group of people known as satoshi nakamoto and was released as an open source program in 2009.
