They have a system that rewards a monthly crypto amount based on the number of upvotes you received that surprisingly has an actual value that you can sell for. It’s largely led to a race to the bottom where comments and posts largely ignore any long form discussions or accuracy in favor of majority appeal.
A post getting 1000 upvotes earns $4. That's already quite a lot of upvotes, enough to get on the first page of a reasonably big sub. Posts on r/all (today, which may be abnormal) are at 10-50k, so would earn $40-$200.
$200 would be nice to have! But these don't seem like prizes that would motivate residents of first-world countries, considering that you have to have one of the most-upvoted posts on the whole site to win them.
In theory I think this would encourage higher quality posts to attract those who upvote rarely.
