This is super,

I've considered using S2F MODEL in studying about the crypto market especially to commodity like Bitcoin and gold.

The pretty definition is outstanding and the formula helps shapes how unique the concepts is.

I so love the advantages you give, and the limitations it has too,
So as a trader it's good to carry proper and well advanced knowledge on a commodity before delving into taking actions.

Your discussion on applying to steem is well acknowledge, I love the way you put it.

Good luck on the challenge.
