"The inflation will continue decreasing at this rate until it reaches 0.95 %, after a period of approximately 20.5 years". After 20.5 years the rate of inflation will remain at 0.95 %. Steem is an inflationary currency and the inflation is predictable. So as long as the new demand for Steem is greater than inflation rate the prices should go up. Since there will be many writers who will flock to Steem blockchain I think that should be taken care. The only challenge is the rewards pool will decrease by that time. But if the steem price has increased by that time it should still be worth a lot in USD.
