Upgrade the 200K to 1M bit badges!
The current badges (recently introduced) for the 200K, 300K, 400K ... 900K and 1M milestones are pretty dull.
Here they are: https://i.gyazo.com/a0b1bcbc58a7de87d0ea5ecc5772e5b4.png
I think they could be a bit more snazzy for the amount of money needed to be spent to receive them.
I certainly think introducing an animated bit badge for the 1,000,000 bits milestone would be awesome for the people who are dedicated enough to go for it!
