The world does not work that way.

If you really want to attempt to figure out some short terms BTC price dynamics, then you have to take into account a variety of factors, even some factors that are less than pleasant to account.   

Of course, you don't necessarily need to follow every move, and of course, you could just ignore entirely if you are just buying and accumulating and you don't plan to make any shorter term plays and you might not even care about shorter term dynamics.... People participating in this thread are generally interested in both longer term and short term BTC dynamics, including factors that can affect short-term price including a variety of factors that you seem to want to presume are not relevant.
