Q: How is the Steem Coin supposed to get value?

Hey Steemers!

I´m pretty new here, and I´m still trying to understand the whole construct Steem with all it´s facets.
Actually I forgot who initially brought me here, I think it was someone on cryptocompare.com who said that steem is the next big thing! So I gave it a try and here I am. I understand that it´s still the beta and the Kindergarten time of Steem. Even though it´s so young it radiates self-confidence.

However Hive account@jerrybanfield pointed out in a post of his, that the steem coin will go up to 10 dollars in ten month.
Maybe yes, maybe no.
Personally I don´t know how this should happen?!
Because if I have a look at the eSteem app, and click on "market" i get this

Most of the Steem Coins are being sold by their owners right? Everyone wants to cash out. Few to little are holding it. Even fewer people are buying Steem Coins with "cash" aka BTC. Am I right or is this Chart totally wrong?
Are users actually using the steem coin by sending it between one another?

Where is Steemit getting it´s market capitalization from?

Please help me understand, thanks a lot.

Clear skies!
