Hello dear friend greetings to you, Hope you are having good days there.

You say stock here means the commodity already present or available in the market, and the word Flow means how much new commodity will be added to the market. Yes this is true. Stock to flow model works on the stock of commodity and upcoming stock. You have beautifully explained it's pros and cons.

You are of the view that we can't use it for STEEM Coin, because it isn't a major commodity as Bitcoin or gold. You have beautifully explained why we shouldn't use it for STEEM crypto currency.

The best post dear, best wishes for the contest.
