But what would happen if the oldest and most valuable asset on the market, Bitcoin, dropped to zero?
Anything is possible. I see it like Murphy's Law: Everything that can go wrong, will go wrong. Now you can say: What does going wrong mean? It can be with anything, not just bitcoin. Look at the currency in Venezuela, it's lying on the street and has no value. Look at the inflation in Turkey, people don't want to trade in lira, they want dollars or euros. Bitcoin can only develop in two directions. Up or down, there is nothing else and no one can see the future.
