I don't know why bitcoin is the best future currency, maybe people will discover something new, bigger and better. You will never know what happen in future, that's what i'm thinkign.
That's true anything is possible with bitcoin, either it will skyrocket or simply disappear but we hope that it will reach to a new level in coming years.
