The Spanish regulator CNMV has placed MediaGC on its black list.
MediaGC is a broker that offers trading with currencies, stocks, commodities and cryptocurrencies via CFDs.
The broker claims to be based in St. Vincent & The Grenadines and to be regulated by the Financial Services Authority. But we could not find any proof on the FSA website.
In any case Media GC has no authorization to provide investment services in Spain or any other EU country, this is why the CNMV placed it on its black list.
We recommend trading only with brokers that have an authorization for your country.
