I think technically MEXC isn't available in the US.

I assume you can use a VPN to get around that if they're not asking for KYC... but I guess that pipeline could be closed at some point... which I'm sure doesn't inspire confidence in Hive from people in the US.

I've used SimpleSwap.io through Peakd.com before to convert ETH to Hive... but it was a terrible experience, the transaction took something like 9 hours, which I'm sure was just them trying to get the best possible price to make a profit. You can see panicked people in their Telegram support channel pretty regularly.
