It'll be disastrous if such a thing were to happen because cryptocurrency have become part of our lives, I don't even like to imagine such a scenerio. Losing a valuable investment asset like Bitcoin where people can hodl for years and plan their retirement will be heartbreaking, many people will become hopeless and poor. Many people depends on cryptocurrency as their sources of income from miners to traders and the exchanges, the world wouldn't be the same without it.

I guess that anything that will disappear cryptocurrency will also affect most things that depends on the internet to work. Communication, banking system and the entire social media will also shut down. There'll be so much confusion and it'll be catastrophic, I hope that something like that never happens.
