Except this will never happen, because the Bitcoin market is too large for something like this to happen. A market this large simply CANNOT go to $0.
the market is u forgiving. anything can happen honestly
Agreed, if bitcoin's price from 0 to a thousand dollars is possible, such a journey downwards is also possible though highly improbable at this point in time. Maybe after some kind of catastrophe or some vulnerability in bitcoin is found and is already exploited, chances are this could lead to the massive decline in price with the possibility of bitcoin becoming worthless, again.
