Well, it could be yes but it is impossible. Even though the price is unpredicted, --losing bitcoin value will never happen.
The value of USD is not a factor for the bitcoin to decrease or worst turn to zero. Bitcoin is not backed by the US or USD, it is backed by the demand it had. It is actually another way around. If USD continues to decrease, bitcoin might skyrocket. Why? Because if that is gonna be happening, the demand for bitcoin will then increase. ^{[As simple as that]}
