Which exchange has listed core?

Can you please clarify which cryptocurrency or digital asset you are referring to when you say "core"? There are several projects and tokens with similar names, so without further context, it's difficult to give a definitive answer. Assuming you're asking about a specific cryptocurrency called "Core" or a similar name, the best way to find out which exchanges have listed it would be to conduct a thorough search online. You can start by checking reputable cryptocurrency news websites, forums, and social media platforms to see if there's any information about the listing of this particular asset. You could also use a cryptocurrency tracking website or app to search for the asset by name and see if it's listed on any exchanges. Keep in mind that not all exchanges will list every cryptocurrency, so it's important to do your research and choose a reputable exchange that has a good track record of security and reliability. If you're still unsure, you can also reach out to the project's team or community for more information. They may be able to provide you with a list of exchanges where the asset is currently listed or upcoming listings.
