Explain how this happens? Is the rate constantly growing so fast? Because of which?
It is not clear why the site reduces bitcoin and increases USD? If the rate changes, why not just increase the second parameter? Someone can say why they change bitcoin down and USD up and not just USD up on the site?

This is the market. The price is determined by the balance of supply and demand.

Do you understand your own question?
The rate depends on demand.

It all depends on the speculators

Let's just say the reason is simple: if you can sell more expensive, then why not? if you can buy cheaper - again, why buy more expensive?
Now think: we have two curves - supply and demand. They have a point of intersection - this is the balance.
One side wants to sell high, the other buy low - at the point where they agree, a deal occurs.
