What are things that could actually kill Bitcoin?

I’ve been following this page for a couple weeks now and allready have a very small amount of bitcoin myself but don’t feel like i really know enough about how it works.

Online you can really only find 2 opinions on bitcoin. People either absolutly love it or they totally hate it so i thought it would be interesting to hear what the bitcoin enthousiast think the dangers of Bitcoin are.

So what do you guys think that could actually kill bitcoin?
