i was thinking about this question,
most people here have the 'legit' answers , user adoption, ect...
still -------------- what got it there the last time ?
a good ole fashioned PUMP
I am not in favor of this since wild changes in peoples perception of value can damage the image of btc.
But it sure as hell got the job done last time.
you got it, a pump is the only thing that can boost bitcoin price and force adoption in a short time, yeah it's not a natural grow, but what it really matter is what will happen after the pump
if the price will not crash like the last time then a pump would be ideal now, because besides helping adoption will raise the confidence of people in bitcoin, but as i said, only in the case there will not be a big crash after it
