Consequently, the Lebanese laws do not prohibit the ownership, use, trade of cryptocurrencies, but when it comes to their acceptance as a payment method, regulations only adopt legal tenders/fiat currencies. Thus, the acceptance of cryptocurrencies by retailers, for example, can be ruled under the provisions of barter.
