Why can't i buy XDC on Coinbase?

I've been trying to buy XDC on Coinbase, but I'm encountering difficulties. Can you help me understand why this is happening? I've always relied on Coinbase for my cryptocurrency transactions, but now I'm unable to purchase XDC. Is there a specific reason why Coinbase doesn't support XDC? Is it due to regulatory issues, technical limitations, or something else entirely? As a cryptocurrency enthusiast, I'm eager to diversify my portfolio and XDC seems like a promising investment. However, I'm at a loss regarding how to proceed with my purchase. Could you provide any insights or alternative options for acquiring XDC?
