Of the top 100 addresses; 59,993 have not changed in more than 1 year. 41% of the 146,213 held in the top 100 addresses. 30.5% of the total 197,009 in circulation.

15,077 are government-seized & frozen at Bittrex. 7.7% of total UNO in circulation.

Addresses #101-200 = 10,056 UNO. 5.1% of total.

30.5 + 7.7 + 5.1 = 43.3% essentially out of the picture medium-term. Adding addresses 201-500 or reducing minimum time from 365 days to 100 days would increase that figure substantially. Factoring that some coins on exchanges will only sell at significantly higher prices also shifts it.

Edit: addresses #201-300 = 3866 UNO inactive for > 1 year. 2.0% of total.

addresses #301-400 = 2142 UNO inactive for > 1 year. 1.1% of total.

addresses #401-500 = 1641 UNO inactive for > 1 year. 0.8% of total.

At least 47.2% are 'out of the picture'.
