> Anyone making new predictions of Bitcoin's demise must explain precisely how and why its distributed network would fail.
A systemic banking panic.
Everyone becomes worried about being able to extract money/value from the crypto ecosystem as a whole due to the failure of some exceptionally large entity (Coinbase or Binance or Tether failing).
They all run for the exits at the same time trying to cash whatever crypto they can into currency. With no sort of backstop, no FDIC, no government intervention, no failsafes, etc there's nothing to stop it from all unwinding to effectively zero in a panic. And panics aren't concerned about market efficiencies or intrinsic value or network effects or anything other than the ability to flee into some other unaffected liquid asset. The contagion would spread throughout the network with people trying to take any exit they could find until that exit was shut down.
Given that the crypto ecosystem in general doesn't believe in government regulations to prevent panics it is nearly certain that one will happen, which will bring crypto to a very sudden halt. The probability over time reaches 100%, but it will likely take some kind of precipitous drop from a sufficient height that no individual Billionaire will be willing to step in and buy it all up cheap (previously crypto has likely been "small enough" that a billion here and there was able to stop the crash in e.g. 2018).
It is impossible to predict when it will happen since it requires knowing how much systemic cash is available for withdrawals and how much can be raised, and the timing of financial entities failing, and the appetite for risk of anyone with deep enough pockets to try to bail it out.
And Bitcoin has never really been tested by a recession that would cause it any kind of problems. The V-shaped pandemic recession was cushioned by a lot of injected liquidity in the markets and people switched to greed almost right away after the first bit of panic waned. It has never been stress tested by something like 2001 or 2008 in the broader economy.
