what if someday when bitcoin has become the main payment instruments in the world. and how when the Internet network paralyzed. it means that we all can not perform various financial transactions? , is there any solution ?
Use cash.
It is impossible to happen in our generation, we are in the Information Age, and internet is one of the most needed of people to complete our needs in our everyday lives, and most of the things that we do have these days won't function without the internet, so I guess, it is time to say "
Welcome back to the Old Age" if this thing happens, because everything that is modern would be completely useless without the Internet, that is why this thing is very impossible to happen in the future.
