I aknowledge, that I will be in a world of hurt if crypto fails.
There are one or two scenarios where crypto will inevitably fail. Global nuclear war, and perhaps some kind of quantum computer.
Anyhow I have a hard time thinking of any other scenario than nuclear war quite as devastating for all cryptocurrencies. Super volcanoes maybe?
Super volcanoes could be a thing :)
I see it much the same, which is an interesting thing to consider for those who are selling all they can to survive in the current economy. Seems to me they might be backing the wrong horse.
