I think that only one thing could make Bitcoin's price fall so low and it is simply the invention of a newer, better technology than blockchain. I think that this will not happen for many years, but with such rapid technological development it will certainly happen sometime. Just as financial markets will now adopt Blockchain, so will Blockchain in the future be replaced by newer technology. It is simply progress of civilization.
Well, it is always the problem of sacrificing one pillar to gain something on the other one. Either you sacrifice decentralisation and get more throughput, or you go all the way for decentralisation with 1 MB blocks. You can even see how bad the adoption of all these different Bitcoin forks is.
I just thank Bitcoin Jesus quite a lot for my 16% Bitcoin bonus when selling his fork.
