Op questions looks very funny to me, if bitcoin doesn't exist or if bitcoin falls people will continue saving their money in the bank instead of investing it in bitcoin , if bitcoin doesn't exist saving money in the bank won't add any value, it will be just waste of time. If bitcoin falls many people will missed bitcoin because since the existence of bitcoin many have benefited from bitcoin so much.
What you say is very true because bitcoin is something that everyone dreams of.
And they also never would have dreamed that bitcoin would crash eventually.
Everyone has had a change in their life while recognizing bitcoin, therefore they will continue to hope that there will be a miracle for bitcoin in the future.
