Is it better to invest in bitcoin?

Bitcoin price is going high, as in 3,4 days it went from 8000$ to 9400$.
According to some experts bitcoin will touch 10,000$ to 15,000$ before 2019.
In next five years, I mean before 2024 bitcoin can touch 50,000$ to 60,000$. For long time investors it's better to invest in bitcoin as it will provide you great profit in some time. If you buy 1 bitcoin today, I bet within a year you will get another one becuase bitcoin will never get down from this.
