Bitcoin has been declared dead many times:
It just keeps on existing.
It just keeps on existing.
I don't doubt the faithful's ability to conjure up some other BS story for why it's worth owning, but there has to be something.
This is also true of Boeing, Citigroup and the Argentinian peso.
Looking at the actual quotes on that website, I'm struggling to find the word death (or a synonym). Instead, it's a collection of criticisms. Many of them wrong. But not many showing thoughtless dismissal.
A number of them suggest that it'll become worthless in the future, but that's certainly not saying it's dead now.
Start at the bottom of https://bitcoindeaths.com/posts and scroll up. You will find many prominent declarations of imminent death or failure, including "So, That's The End of Bitcoin Then" (2011), "Bitcoin Sees the Grim Reaper" (2013), and "An Early Obituary for Bitcoin" (2014).
Hope your belief in the system has paid off incredibly well for you.
That is not in itself a recommendation. You could say the same of most infectious diseases and parasites, or antisocial acts.
I wish COVID had that ROI.
It had it... for some, same as BTC.
