What can CRO be used for?

Could you please elaborate on the various uses of CRO? I'm particularly interested in understanding its practical applications in the realm of cryptocurrency and finance. Is it primarily used as a means of payment, or does it serve other functions as well? Are there any specific scenarios or industries where CRO finds its most frequent utilization? Additionally, how does its usage differ from other cryptocurrencies in the market? I'm eager to gain a deeper understanding of its functionality and versatility in the current financial ecosystem.
