As of today, bitcoins price has increased more than 50% from when i first discovered bitcoin  and i was still a newbie then. And if only i knew how it works and has money to invest in bitcoin, I think it would have been the wisest decision to make. Imagine that in the next 5 years of investment in bitcoin, its price rises to maybe triple its price now. It would be better than investing in banks which will give you less than 50 % even after 10 years.
