I can imagine the sizes of the dots changing soon, I'm surprised they all seem so even with the investors we have getting extra multipliers. That and new people joining, others leaving..etc. It seems pretty consistent through out but give it a few more AD's and im sure a bigger difference will be seen.
Yeah, I was surprised about the even distribution, too. Now look at this

The large dot represents the largest airdrop recepient (~8,000 PRIV in 7 drops), the one next to it is one of the smaller ones (638).
There will be dots that stand out more over time, especially those of early investors and HODLers.
