I tried to make a research for my university when I was finishing my studies and had the same problem.
There is not so much research around bitcoin and blockchain from the universities. Mostly, companies that move around fintech has written essays and articles about that which do not make valid sources for a university citation.
If you are really into the use of bitcoin, you should make your own research. If you can't find one, then start one.
Making researches about bitcoin can make most of the educated person to become familiar about the uses of bitcoin, advantages, and its benefits in the market. It is much better if universities would try to implement blockchain as a course or subject, and I just read it in some threads here in this forum that if they will try to do that, college students will have a prior knowledge or basic ideas about cryptocurrency.
I think the main purpose of creating bitcoin is like that, satoshi nakamoto wants to create a digital currency that cannot be controlled by others, so only those who have bitcoin can control it and can be used as the safest and fastest transaction solution.
But if it is centralized, government will not agree with that. That's the reason why government is still not prohibiting the use of bitcoin due to its centralization, they can't track bitcoin transactions.
