It's important to note that the name "tsuka" isn't widely recognized in the cryptocurrency space, so it might be a specific token or project that's not well-known. That being said, if "tsuka" is indeed a cryptocurrency or token, the exchange where it's listed will depend on several factors such as the token's popularity, demand, and the willingness of exchanges to list it.

To find out if "tsuka" is listed on a particular exchange, you can try searching for it on the exchange's website or using a cryptocurrency tracking website that provides information on exchange listings.
