How to Earn Moons?

Can anyone tell in simple and short sentences “How to Earn Moons?” 🙂

Some of the community members here have thousands of Moons which is amazing while I have only about 200

And can Moons only be earned here or on all the subreddits?

I believe Moons has a great future when Reddit will be adding more utilities to it as we advance into the world of Web3 and it can be very rewarding accumulting some Moons while we are on earth before Moons goes to the Moon.

250 Million max supply sounds somewhat less.
