Burning can perhaps create scarcity and drive up demand and price however burning should not be an answer. I agree with @knircky, if there was a clear cut reward for active users everything would look up for steem. Investing more into what and who is already invested makes more plausible sense. Trying to burn and neglecting what is already, may be greedy and neglectful. I don’t believe burning will increase value it may increase scarcity but if the people that believe in the project no longer hold it as valuable it won't matter how much of it there is, if they all decide to abandon the project. I believe in building from within rather than trying to make things look good from the outside i.e burning coins to increase demand. How about increasing interest and thus increasing demand. Steem has to have a niche; a use, a project, a reward, something that pulls in interest and users and demand. IMO
