At inflation rate of 1% that will be in 18 years STEEM price has to be MUCH higher to incentivise people to hold STEEM in SP mode. If Steemit(and all other versions) is successful and worldwide used at that time, then price will be HIGH and 1% rate will be OK. If Steemit has at that time current market cap of Facebook, STEEM price will be 900$. At that price 1% inflation is perfectly fine...
