I am sure most people don't do contest for the bonus prizes but for the experience. It also seems that contest rankings are quite consistent so I won't be surprised at all if the top contestents have maybe 10 Apple HomePod Mini from just participating through the contests.

So why isn't leetcode sharing the fun? It would be interesting if they added bonus prize categories for "first time" prize winners. What counts as "first time" could maybe refresh in a year or so. :)
