Serious question, how do people get so many moons?

Hi, question as title.

I see a lot of users with more than 10k karma which this month would mean more than 2800 moons, or considering today price, more than 400 USD!

As you probably know I live in Venezuela, where monthly minimum wage is 3 USD and considering some NGO, a 5 members family could “live” with that amount monthly!

But, taking Venezuela out of the question. 400 USD is more than the monthly minimum wage of almost all latin american countries (maybe excluding Panama and Chile!), and this is considering still moons aren’t in the mainnet.

This is almost incredible hehehe!
