Yes dead many times or rather few times. Bitcoin cant be considered many times just because its currently down. I still believe as the very first crypto it still potentials. Bitcoin i can say is a sexy currency 
if you know what i mean, it lunched all these other currency even though other cryptos will have higher values at different times. I must also say investments on cryptos should carefully taught about along with proper understanding of the crypto of interest
