Bitcoin is traded by its users all over the globe, all through out the day. It is not an asset controlled by any central authority to regulate its price. Rather the price is kept in motion by its traders. Hence the very thought of such a question shows that your knowledge about bitcoin and how it works is pretty weak.

What you can have is Support/Resistance levels but these are not absolute and these are not permanent. They break and consolidate when the market closes in on them. They are only indicators of certain levels.

If you want, you can create a pump and dump group just another hundred others out on the network. But it solves nothing. Prices will rise and fall - that is what speculative trading is for.
