Hmmmm.. if crypto disappeared tomorrow, it will shake things up oo. For those who have invested a lot of time and money in the space, it would mean loss of assets and income streams, which will be hard and almost impossible to recover from. People who rely on crypto trading, mining, or staking will need to find new ways to make money. Still though, daily life for most people might not change much, since crypto is not yet fully mainstream, the impact will just be on those who built businesses and communities around blockchain technology, as they would need to pivot really fast.
Side thought though;
If i'm being honest, to summarise and based on my intrusive thoughts, "There might be war"
I totally agreed with you, there shall be a lot of war and crime and corruption will still be multiply if crypto disappear today because most people life depend on it for survival, because some people turn a new leaf ( that is from there negative way) which we have been enjoying peace of mind and as for me, I have been benefitting and it has also saves me from a lot of financial issues, which I'm always thankful to God for giving us the knowledge to know about bitcoins.
So I never think or imagine of that to happen and I'm always praying to God, not to allow crypto to disappear, if it disappear today, there shall be absence of harmony, more of suffering etc and most people might be those all sorts of things just to survive.
