The Spanish National Securities Market Commission (CNMV) has added 23 unauthorized forex and cryptocurrency entities to its warning list on Jan. 14.

Among the companies added to the list is Blonde Bear OÜ, also referred to as Black Parrot Ltd., which claims to be a forex and cryptocurrency exchange operator but reportedly operates in Spain without a license.

The company, which operated on the trade111.com and tradex1.com domains, has also been flagged by the Polish Financial Supervision Authority for operating in Poland without the required license.

Another company added to the CNMV’s warning list is Dax300, also known as Brown Fox Ltd., for operating in Spain without a license. This company is involved in the trading of contracts for difference (CFD) tracking cryptocurrencies, commodities and forex.

As Cointelegraph reported in December last year, Spain was among the seven countries which have signed a declaration calling for help in the promotion of Distributed Ledger Technology’s (DLT) use in the European region.

Also in December 2018, Spanish renewable energy company ACCIONA Energía announced that it planned to deploy blockchain to trace electricity generation.
