How can topic about Bitcoin be way to narrow? I don't get it. You can write about the blockchain technology in essence. You can write about its decentralized nature and why is it important for the world -snip-.
I gave you just some pointers, there is really so many things to write about out there. Just use your imagination and research.
I want a specific question as to which I will do my research on, most of your point here is related to Economics while I'm doing a Comp. Sc. related essay.
Ok, I see, my bad! Here is a possible good one. Possible influence of quantum computers on Bitcoin in the future. Is Bitcoin secure if quantum computers do show up?
Hmm, that and the earlier idea combined might just be it. Thanks for the contribution
