Is CommonDigital a safe option?

No, CommonDigital is risky.

The broker claims to have offices in both the UK and Luxemburg. However, there are no corresponding records from the UK's Financial Conduct Authority (FCA) to support its legitimacy in the country, and the Commission de Surveillance du Secteur Financier (CSSF) of Luxemburg has issued a warning against CommonDigital, noting that the entity is not under their supervision.

Therefore, CommonDigital cannot be trusted. Investors dealing with it may run risk of losing their funds without a way to get refunds. To have a safer trading environment, it is strongly advised to choose fully regulated brokers over unregulated ones like CommonDigital.
