All accounts owning more than 10,000 vested XEM have a non-zero importance score.
With a supply of 8,999,999,999 XEM, the theoretical maximum number of accounts with
non-zero importance is 899,999.
In practice, the number of actual accounts with non-zero importance is not expected to
approach the theoretical max due to inequalities in held XEM and also the temporal costs
associated with vesting.
