Andone has a subscription to https://nomadlist.com/? Is 500 USD worth it?

If you want to work remotely around the world, yes. But I wouldn't pay 500 USD for it. It isn't very useful for travelling as a digital nomad within India. There are at least a few dozen people here you have access to Nomadlist. I paid $99 for the lifetime membership. It shows up going for $79 right now. Not sure shows up for $500 to you.
