What about bcc value?
I mean if for exemple btc is 2700 dollars the 1st of august , BCC can't be 300dollars or btc should decrease at 2400?
Is this the right way of looking at BCC?
Once a coin "breaks off" from another coin, it's value is free to be set or manipulated
independent of the original coin.
So "no" (to your question), b/c these prices are "perceived" value (short-term, sometimes "in-the-emotion"). They have been set by individuals/bots/exchanges, which are then bought by other individuals/bots who are "willing" to pay that price.
But "yes" to your assessment toward total real market value (long-term, when hindsight is more 20/20). Because this UAHF will be in "direct" competition with the originating coin.
What they/we are actually getting can be a different story, which usually plays out in-time vs in-the-moment.
It's not too unlike some of these exchanges or ICOs we've see, with little -- if any -- history. Some of them make massive gains, only to disappear with people's money into a black hole of private, privileged vacations or unending "extended" stays in remote locations such as Caribbean Islands or even China (Big Vern). But trust me, that value -- that "money" -- came from somewhere. Whereas other exchanges or ICOs are (or show themselves to be) more legitimate.
