Time Series Analysis Project

[yomanwatch]

Hey guys first time poster. I currently have a project in my time series class and I want to do it on daily prices of Bitcoin for the past two years. I'm having trouble coming up with a scientific questions for my analysis. Initially my question was "Is it possible to predict bitcoin prices?", I find this a bit bland and vague. Anyone have any ideas? Please help.

An interesting question may be: is btc price correlated to difficulty of mining?

Is this for high school or college? 

(also by the way, the answer to your question should be no.  If you can reliably predict BTC prices, then you can very soon be a rich man)

How about this:
If 75% of bitcoiners are accumulating and 25% are spending, how long until group a has all the coin?
Follow-up question:
In the above scenario, how long until stores that accept bitcoin stop accepting them because it isn't worth the hassle since very few sales are happening?
