Can I buy Avalanche on Metamask?

Could you please elaborate on whether it's feasible to purchase Avalanche tokens through the Metamask platform? I'm interested in adding this cryptocurrency to my portfolio but am unsure about the specific steps involved. Is Metamask compatible with Avalanche? Are there any particular requirements or considerations I should be aware of? Would it be advisable to use Metamask for Avalanche transactions, given its reputation and security features? Thank you for your assistance in clarifying this matter.
