What does Giottus do?

Could you please elaborate on the functions and services offered by Giottus? I'm curious to know what sets them apart in the cryptocurrency and finance industry. Are they primarily focused on trading, custody, or do they offer a comprehensive suite of solutions for investors and traders alike? Additionally, how do they ensure the security and safety of their clients' assets, and what measures do they take to protect against potential risks and vulnerabilities in the ever-evolving digital landscape?
