  1. What is the bitcoin?

The Bitcoin is the first ‘Peer to Peer’ decentralized payment network that works thanks to its users. The bitcoins are transmitted from an individual to another, so there is no public or private intermediary.

It is a digital currency that circulates on the Internet. It is at the same time an electronic currency and a free trade protocol. The bitcoin has no legal rate, no one is required to accept payment in bitcoins. It is a currency that ‘results from usage. ”

  1. Who has created the bitcoin and when?

This virtual currency was created in 2008 by a person (or entity) known as Satoshi Nakamoto. But to date, we still do not know who created this currency, or where it comes from.

  1. How can we obtain bitcoins?

Several possibilities are available to obtain bitcoins:

  • You can buy it against common currency on exchange platforms (or marketplaces). Fifteen are available in the marketplace (Paymium marketplace in France). An account in euro and an account in bitcoin must be opened.
  • You can receive bitcoins by actively participating in the monitoring of the currency. Therefore, we participate in the mining process. These network controllers validate the transactions and are paid according to the machine power provided by each miner to the network.
  • You can also buy them or sell them on platforms from one person to another.
  • Finally, the House of Bitcoin has a currency exchange that enables to buy bitcoins against euro.
  1. How does it work concretely?

To perform transactions in bitcoins (purchase, bitcoins transmission or receipt), you must have an e-wallet (wallet). It is a software that you must download and it generates another one in form of a unique algorithm. The digital portfolio consists of two parts: a public key to receive bitcoins and a private key that will be used as a digital signature to debit the account during your transactions (payment of goods and services, purchase of bitcoins, transfer of bitcoins).

The issuance of bitcoins does not fall within the scope of any organization because it is generated by a computer program. The program specifies notably the issued quantity of the currency based on a predefined pace (21 million bitcoins generated in total by 2140). Today, the number of bitcoins reached 13 million bitcoins and this pace is divided in two every four years. The bitcoins are the result of a competitive process that is called mining.

The bitcoins are designed to self-regulate; the smooth functioning of trade is guaranteed by a fully decentralized network that everyone can examine because it is public: basic protocols, cryptographic algorithms used. All the accounts and their balances are stored in a file; the blockchain that can be accessed by everyone.

They must have been victim of a hack. Bitcoins were stolen and 46 million euros disappeared.

  1. What about the French regulation in front of the Bitcoin rise?

The currency is not subject to any public authority and is not regulated by a central bank. Hence the state authorities are a little concerned by this matter and they are trying to regulate and monitor this virtual currency. Following the Tracfin report of July 2014 on virtual currencies, the Finance Minister Michel Sapin wants to regulate this type of currency and promote the emergence of a framework to prevent and deter its use for fraudulent purposes or money laundering.
