It is curious that the peak of that chart is in 2017. I think that was the height of the blocksize wars, with the hard forks of shitcoin cash and others, aside from the danger of flippening that there was with Eth eating into Bitcoin. But we see after the years that the danger passed and Bitcoin continued to be declared dead without anything really happening.

Looking at the downward trend, if next year we enter the bull market as expected, the death of Bitcoin will hardly be announced.
