University research paper on crypto

I'm making a brainstorming for the topic of a university research paper on the factors that determine the price of bitcoin.

I thought of some factors like the stock market, the price of gold, the interest rate, even the impact of tweets on the price of the bitcoin.

The problem is that there are several other research papers are done on these factors.

Does someone discovered a factor that is not too popular.

If someone proposes me a good factor I can show him the study results when I finish it ????
