Just because of recent drop you cannot say that bitcoin is dead. Just think about it, btc came all the way from 1usd to 20K which meand 20.000 times more and then it dropped to 9k, it is still 9000 times more.
Yes and i think Tulips did this too but they never started of at $0.02 like Bitcoin stayed at for years so that 180,000 "times more"
