It is not too late to buy some bitcoins. You can see that bitcoin is at the moment rising it was 3200 dollars a month ago. Now it is 4450 dollars worth if you had invested then you would have some profit. I have invested in bitcoin so I have now more money I am waiting to bitcoin to hit 10k dollars. I would have a lot of money.
Agreed , I think bitcoin is still far from its peak, so its not late. Unless some serious regulations or new tech comes in, which would hinder bitcoins wider adoption. I say: buy it
