How does a CRO make money?

Excuse me, I'm quite curious about the financial aspect of cryptocurrencies. Could you please explain to me how a CRO, or Crypto Return Offering, actually generates revenue? I've heard of various models in the crypto world, but I'm still a bit hazy on the specifics of how a CRO operates from a monetary standpoint. Would it involve staking rewards, transaction fees, or perhaps some other innovative mechanisms? I'm eager to learn more about this fascinating aspect of the crypto economy.
