Things could be as easy as reaching  the new heights just the same way bitcoin did it last time. But now its the time where we have to overcome few of the challenges for example, scaling up issues. This is over the head now and as we can experience, the fees, trasanction speed and confirmations are taking a lot of time. Even after paying the amount of 40-50 USD my transactions are taking longer than half hour which is insane thing. You tell me how people will believe the BTC now and how they will get into it easily? They don't just want to make profit here but they also need some useful stuff with bitcoin for example, faster transactions. This is the sole purpose of the BTC which we re not able to achieve. So lets see what happens in the long run and give bitcoin few months to rise again if it could then we can start speculating about the 25,000 K prices.
