Can I buy Harmony One with Ethereum?

Excuse me, I'm considering investing in Harmony One, and I'm wondering if it's possible to use Ethereum as a means of purchase. Given the current crypto landscape and the various exchange platforms available, I'm not entirely sure if this is a viable option. Could you please elaborate on the process? Is there a specific exchange that facilitates this transaction? Additionally, are there any potential risks or fees I should be aware of before proceeding? Your expertise in this field would be greatly appreciated in guiding me through this decision-making process.
