cash is not going to die, at least not in our lifetime but what does that have anything to do with bitcoin? bitcoin was not created to kill anything! besides who cares what the "bankers" think about bitcoin, it was not created for them to use. it was created so that people don't need them if they chose to spend their money. so that they have an alternative method that doesn't require these third party parasites that can only live because people need them.

don't worry in a couple of years they will have enough time to beg others to teach them how bitcoin works and beg people to come back as their business starts to fail and they start needing another bailout.
