There is only two ways:
Maybe Bitcoin is unsuccessful. Then it's 100 % loss.
I don't see how you can stop Bitcoin? There will always be a market for illegal drugs or purchases of a private nature online...
You can't stop it. I am talking about the case that it does not get main stream because the public does not want it.
Ok, well given it's not even in the mainstream now then I doubt it would result in a "100% loss" if that happened. I dunno... I just think there is a strong possibility that the BTC/$ chart will resemble the AAPL/$ chart.
