2011 was when Mt. Gox was hacked and had 647,000 Bitcoin stolen. I wouldn’t have blamed anybody for having a pessimistic outlook after that incident.
You possibly only knew about Mt.Gox by reading history of Bitcoin and Bitcoin market, so this information is not quite true. Because your account was registered in October 2018, so I believe that a highest chance is you were not in this market in 2011.
In hindsight that statement seems absurd because of how much Bitcoin has grown in the time since. Institutional adoption of Bitcoin was only a fantasy back then and you might have even been called delusional for thinking that it would one day become reality. Now it’s the complete opposite.
Now it’s the complete opposite. Anybody saying Bitcoin is dead or is going to die seems like a charlatan or a crazy person. Sometimes those detractors get platformed by mainstream outlets, especially after there’s a major price decline, but the anti-Bitcoin propagandists always end up being proven wrong.
There are individuals and institutions which both have contributed to Bitcoin adoption and with people who understand about Bitcoin, any call of Bitcoin is dead is crazy even years ago, excluding very earliest years after Bitcoin Genesis Block. I consider years after a first Bitcoin halving are when any "Bitcoin is dead" call became crazy and unreasonable.
It's part of Bitcoin growth with support of Lindy effect with time, then development increase, adoption increase, better security, value growth, and trust growth.
