I dont think this is true though. The % of wallet owners is totally misleading based on the amount that are abandoned/empty:

if you look here there are apx:
235 users owning 35% (10mil +)
26,000 users owning 50% (100,000 - 9,999,999)
90,000 users owning 7% (1,000 - 99,999)

then the rest is where-ever.

Still not an even spread, but theres never going to be at this early stage.
