What is the real name of Saber?

Could you please clarify for me, what is the actual, full name associated with the pseudonym 'Saber'? I'm interested in knowing the true identity behind this individual or entity, as it seems to be quite prominent in the cryptocurrency and finance community. Is there a specific reason why they use this particular name, and have they ever disclosed their real name publicly? I'd appreciate any information you could provide on this matter.
