Cryptocurrencies are currently banned under Algerian law.  The 2018 Financial Law of Algeria has prohibited the use of any cryptocurrencies.  It stipulates:

The purchase, sale, use, and possession of so-called virtual currency are prohibited.  A virtual currency is one used by Internet users over the Internet.  It is characterized by the absence of physical support such as coins, paper money, or payments by check or credit card.

Any violation of this provision is punishable in accordance with the laws and regulations in force.  [1]
