There should be a one-time goal for holding a gigantic amount of starbits. Like a BILLION starbits! There could be no ingame earnings, letting the holder feature something in the game's website for a month, maybe? Something not-so-silly like that. Once per person though! A weird, mostly useless, but fun suggestion.
I am a Rising Star millionaire, holding 1 million starbits at level 50. This enables the STARBITS Millionaire quest once a day, which earns me 10k starbits every time for 65% energy. Starbits earned this way are spent buying packs. One card is given away every single day.
Giveaway goal: Make giveaways for Slippy. 3/9
