How would you be affected If cryptocurrency is banned worldwide..?

[Shortie]

The government would not be able to ban crypto worldwide. They've already tried banning it in a selection of countries and it's failed. Banks and other providers are blocking Crypto payments, but there are other ways to obtain crypto. For example, mining or doing exchanges with other users.

I was not aware this was something that had already been tried, to ban crypto worldwide. 

I have looked into mining myself in the past but that has confused me and exchanging and trading is something that is new to be as well. 

I wonder if the government would ever be able to do anything to have more control over crypto. I would think that would be their next step if they were unable to ban it.
