Nowadays I think the only way to get more users on Steem is to bring the price back to at least over 1 USD

I agree and while I think it will go up and down significantly, it would be good to continually raise the floor price to the point that it is always going to be over a dollar as I think that is some kind of psychological barrier for many.

Could be reason to decrease the inflation of Steem itself or delete the POB and delegate it to SMT tokens. Just a few thoughts.

I think both of these things are in consideration and SMTs are going to bring in a new dynamic that could in time see the value pushed out to them anyway.
