Is my money safe with Nexo?

I'm considering investing in Nexo, but before I do, I need to ensure the safety of my funds. Could you please elaborate on the security measures Nexo employs to safeguard clients' money? I'm particularly interested in how they handle encryption, storage of private keys, and their compliance with regulatory frameworks. Additionally, are there any recent audits or security certifications Nexo has achieved that I should be aware of? I want to ensure that my money is in safe hands before making this investment.
