its not over yet and I must say you tried in your write up but at the same time you where too narrow to think that 2017 was the best year of bitcoin because the best is yet to come and bitcoin is here to stay.
I believe it is not the death of bitcoin although it is struggling daily but it can survive. Yes bitcoin is still here and will continue to stay and will exists. Price of bitcoin stuggles but now we can see a good movements.
