curious about nexon's cash cow (cubes)

Is it about money, or about cubes? I'm not translating into money because I haven't spent a dime on this game, but every 1000NX used gets Nexon $1 richer, so year, confused.

hate posting this many times in a row. part of my message didn't come out of my fingers when i was writing it, sorry.

money (american) or nx, doesn't matter. i just want to get an idea of how much people are spending.

only include nx that you have paid for or gotten through the mts. offers and maple points aren't valid for what i'm looking for.

$581 as of this post (assuming they're 1200 nx each) and taking only the lowest approximations.
