Can I buy Aptos on Coinbase?

Could you please clarify for me, is it possible to purchase Aptos tokens through the Coinbase platform? I've been hearing a lot about Aptos recently and I'm quite interested in investing in it. However, I'm not entirely sure if Coinbase supports Aptos transactions. Could you enlighten me on this matter? If Coinbase doesn't offer Aptos, do you have any recommendations for other reliable and secure platforms where I can buy Aptos? Additionally, are there any specific steps or considerations I should be aware of before making the purchase? Your expertise in the field of cryptocurrency would be greatly appreciated. Thank you for your time and assistance.
