Moons are based on PoS, Proof of Shitposting.

There are some cryptos based on PoW algorithm, means they need to be mined (like BTC and ETH). Then there are cryptos that you get by stacking, and this system is PoS (like BNB and ETH 2.0). But now there's a new PoS model, Proof of Shitposting, you just need to make some random post and you get it, you'll get Moons for shitposting.

PS. Not all posts are like that, in fact I find some posts really useful, but most of the posts are like that.
