The virtual currency Bitcoin beat its historic record last Thursday by reaching 5,247.02 dollars. When launched in 2009, a bitcoin cost only a few cents, and even at the beginning of 2017, it was only $ 966. Since then, this self-regulating virtual currency, which preserves the anonymity of its owners, has seen its course progress continuously.
The bitcoin is based on blockchain, a technology that uses encrypted and authenticated transaction blocks that add up to each other.
This blockchain is reputed to be tamper-proof because, in order to modify information, it will have to be changed at the same time among all users, a feature that is of great interest to the banking sector.
