redditors need to earn at least 10 gold within a 30-day period — if they don’t reach the threshold, the balance rolls over. For users with between 100 and 4,999 karma, they will receive $0.90 per 1 gold. Once you earn more than 5,000 karma, you can earn $1 per gold.
It's so bad... and what will happen is spam cheap bot content to get the gold amount necessary to get paid.
Dollars? That seems optimistic to me. It would probably be an amount comparable to the change you’d find on the ground in a parking lot.
If you’re an extremely active user who has no life, and posts all day every day, then we might be talking dollars. Perhaps even double digits over the course of a year!
