Damn that statistic shocked me!
"Bitcoin has died 415 times.
If you bought $100 worth of Bitcoin every time, you'd have $95,967,142.33 right now."
Bitcoin has never been death. Bitcoin blockchain has never stopped working since 2009. Bitcoin blockchain has never had any blockchain roll back like Ethereum blockchain.
What has died in history?
"Bitcoin is death" died many times because of Bitcoin strong survival with time. All past "Bitcoin is death"s now all died.
I think it was said metaphorically - nothing related to BTC itself didn't die, and it itself became only better.
