Dan: Compared to what we have today, the supply will be heavily limited. The long term inflation rate will be less than 1% which should be hit in about 20 years.
The long term supply will be about 639,276,802.000 STEEM after 20 years. If STEEM goes up in value over that time then the supply may be lower due to Steem Dollars converting to fewer STEEM over time. If STEEM goes down in value it may be higher for the same reason.
