Can you predict what will be the cost per Bitcoin by 2019 Dec?
My Prediction: Around $35,000-$40,000 USD
That was a very impressive prediction man but to tell you honestly, December 2017 bull run will never gonna happen the same way again. IMHO Bitcoin price would play around 8k to 12k in the coming years. And one thing for sure Bitcoin will stay forever.
The thing with BTC is, it is unpredictable. This is what the market makers feel. They trick the chart readers as well. I feel 2019 will surprise all.
