I really enjoy economics. There are so many different things to consider and so many ways to earn more money/value. If you know more of the ways, you're able to make better choices and (hopefully) profit from those choices.
Yes, the supply is always inflating, so there's downward pressure on the price because of dilution, but as the years go on, there will be less Steem created from inflation, as you showed. If Steem survives and grows, it would be easy to see how Steem could be worth much, much more than it is today, especially if there's more demand for it.
