It's about law of supply and demand.
if that's a yes, then does it mean that if everyone take a pause from buying or selling for like a week or more, the market will stand still? A good explanation will help me understand this thing better.
Yes, the market will stand still if there will be no buyers/seller at the period of a week. That is because the network will still remain healthy and secured due to the miners continue to mine. Since you have not mentioned them, it means that mining is still going on and the market will still stand because of them. It's not a long explanation and a brief one that can help you understand a bit of what might happen then.
Miners should never be overlooked. They are the source of bitcoin, so as long as there are miners, the price of bitcoin will never be compromised. However, if there are active sellers and buyers in the market, much better. There will be a constant price update for bitcoin, and that’s a good thing for a healthy market system.
In general, the miners, the active buyers and sellers determine the price of bitcoin. If they stop their function, the market will be stagnant and empty.
