All those trolls announcing the death of bitcoin appear in bear markets like this to spread FUD for two main reasons:
1) They already sold (bought high, sold low) and they are scared of the idea of bitcoin going up again.
2) They never bought but could have done when it was much cheaper, like 3 digits, and they are resentful towards those who bought.
In the meantime, HODL, HODL, HODL.
