Regulators from Mauritius and Switzerland have put Coinoptions Trade and STC on their black lists.
CoinOptions Trade claims on its website that it is regulated in the US and Cyprus, so it can offer Forex and crypto trading. But it is not true.
According the regulator FSC it also claims that it is registered in Mauritius, but it is not true either.
The same problem is connected to Suisse Trade Center (STC), which is a Forex broker that claims that it is based in Switzerland, Cyprus and Belize.
This broker is not regulated anywhere, this is why the Swiss FINMA has published a warning about it.
For your trading use regulated brokers only.
