Strangely, there are over half as many investors between $25 and $50, which means they account for more of the invested dollars.
Again, there are over half as many investors between $50 and $100 as 25-50.
Which means, the whales are where the money is at.
I'd quibble with your definition of "whale" here (if you use it for $100 what would you use for the $1k / $10k tiers which do fill up for some projects), but "Higher price points are worth more gross revenue" is a) useful to know and b) entirely in line with my expectations.
For Kickstarter projects, maybe your low-denomination tier is more about expanding your marketing reach than it is about the money it raises directly.
I looked at a few funded projects with large tiers; the bigger donations were often friends and family. So not really fair; they didn't need kickstarter to get that money. I'm not sure there are any real whales at all.
