Well you forgot one thing dude. It is now almost at the price range of diamond, 1 carat of diamond.
Investing in bitcoin is for long term. Because the price of it is increasing up to the point of comparing it to the price of 1 carat of diamond. So its really worth to invest it now and its never to late. By the next couple of years bitcoin might be reaching the 2-3K USD or more. And mass adoption is also there so its better to invest in bitcoin because its gonna be worth in long term.
If you want to be among The richest people on earth before 2020 then buy bitcoins now and hold. The way price is pumping up this days I think very soon maybe some where before the end of 2017 bitcoin might be trading above $2000. May the gods of bitcoin be among us.
