A Brief History -
April 2018 - Bitcoin Price - 9000$
April 2017 - Bitcoin Price - 1300$
April 2016 - Bitcoin Price - 450 $
April 2015 - Bitcoin Price - 225 $
Yes the jump from 1300$(2017) to 9000$(2018) is abrupt and defies all logic. But then every time Bitcoin is pushed below that level it once again comes up to 9000$ Mark, just like Bollywood Hero who refuses to stay down.So it is safe to assume that this years base price is 9000$
Every Year it seems to double its value, so if this April its around 9000$ it could easily rise up to 18000$ by April 2019.
If it crosses 20000$ mark and creates even more media hype,more new people will hook onto it taking it even higher.
Total Number of Block Chain Wallets is around 2,39,52,849 = Aprrox 24 Million , Total world population is around 7.6 Billion. That is Bitcoin penetration is around 0.31% of Total Population. Every year the Number of users or investors doubles, so in a couple years, as the user base expands the price will rise.
These are Just some possible scenarios or nonsensical thoughts. You may or may not agree to it and you should not take this as a Financial Advise.
