I think this is a non issue. The price will find its true value, sooner or later.

People have been saying that at 0.5$, 0.4$, 0.3$, 0.2$. Now the price is lower than before the launch. How do you explain that steemit's value was higher when nobody even knew if the platform was working?

Once there is a tiny uptrend the price will explode again, as when there is any demand there is little supply.

That won't be the case next time, people have been powering down for months in anticipation for the next rise so you can be sure it will be short lived. Many people are holding off selling for now but still the price is crashing.

For speculators the inflation does not matter as they only look at short term. They are not holding for a year.

It does matter because when a currency has so much inflation there is no market for it, speculators are running away. No one wants to touch a currency that is losing 10-15% of its value every couple days. That's way too risky.

The reason why SP work well I think is be a use investors really need to be invested long term and for that they get a real stake with voting right and influence. I think that is very important.

There is no need to lock people's wealth in order to get them invested long term. All you need is a project that is sound with a sustainable model and an investment that gradually grows in value.
