How much does core cost?

I'm curious, could you please enlighten me on the cost of the core? I've been hearing a lot about it lately in the cryptocurrency circles, and I'm really interested in understanding its value. Is it priced similarly to other cryptocurrencies, or does it have a unique pricing mechanism? Also, do the costs fluctuate frequently, or does it remain relatively stable? Your insight would be greatly appreciated as I'm eager to delve deeper into this fascinating topic.
