Can I buy SingularityNET on Coinbase?

Could you please clarify something for me? I've been hearing a lot about SingularityNET lately and I'm interested in investing. Is it possible to purchase SingularityNET tokens on the Coinbase platform? I've used Coinbase for other cryptocurrencies in the past and it's been a reliable exchange for me. However, I can't seem to find SingularityNET listed among their available assets. Is there a specific reason for this? Or am I missing something? I'd appreciate your insights on this matter. Thank you in advance for your help!
