Is First Digital USD safe?

Could you please clarify for me the safety of First Digital USD? I've been hearing quite a lot about it recently and am considering investing. However, given the volatile nature of the cryptocurrency market, I'm cautious about taking any risks. Could you share with me any insights on the platform's security measures? Are their transactions encrypted and protected against hacks? Additionally, how reliable is their customer support in case of any issues? I'd really appreciate your expert opinion on this matter. Thank you for considering my query.
