Can I buy Avalanche on Coinbase?

Could you please clarify for me, is it possible to purchase Avalanche tokens on the Coinbase platform? I've been hearing a lot about Avalanche recently and am interested in adding it to my crypto portfolio. However, I'm not entirely sure if Coinbase supports its trading. Could you provide some insight into this matter? Also, if it's not available on Coinbase, could you suggest other reliable exchanges or platforms where I can buy Avalanche safely and securely? Thank you for your assistance.
