The way you explain this S2F Model is really interesting.

Definitely in crypto market, demand results in scarcity when flow is less and definitely mean a bullish in market prices.

While Supply that shows high percent availability of a commodity definitely means bearish.

It's advantages are super and premium but disadvantages are to be considered well during analysis to get best results.

Your perspective in applying the model to steem is highly rated to me.. this two behave differently in market and got different mechanism, so if to be apply to steem then the concept must be deepen than this.

Good luck sir
