It seems to me that bitcoin is developing much faster and the price by 2020 may exceed $ 50,000.
Now it seems very ridiculous and bold, but the crypto currency develops its own way and the price increases several times a year - it's real
I don't think its not the development but people are really seeing bitcoin as a good platform for invested that's why the price has skyrocketed for this year alone. So all price prediction could happened. This year alone, bitcoin has grew more than 300% so imagine what the price could be in the next 3 years. If this trend continues we might see $20000 or more in the future.

So I speculate that we are really going to touch this price barring no such drama that will negatively impact the current market trend. So it makes sense to really hodl on our bitcoin and just wait for the next halving because the price might double or triple by that time.
This is also another factor that would put bitcoin and its price to greater heights. And as the network continues to grow and solidify, it becomes clear that even an event as jarring as halving can only reassert bitcoin’s continued existence and the price going to $10000 or higher. IMHO.
