Steem inflation rate decrease roughly from 10% to 1% in 20 years,

but
roughly regardless of the inflation rate decrease, ?

Steem block genration reward is about 1.5 Steem every 3 sec.
about 50 k Steem everyday, 20 M Steem every year ?

while Current total is about 275 M Steem.

Interesting and important point.
