What is a CRE strategy?

Excuse me, could you please explain to me what a CRE strategy entails? I've been hearing a lot about it in the cryptocurrency and finance circles but I'm still a bit hazy on the specifics. I understand it has something to do with investment and risk management, but I'd like to have a clearer understanding of how it works and why it's considered an effective approach in this field. Could you elaborate on the key elements of a CRE strategy and how it can benefit investors?
