People really need to stop asking this kind of questions, we all know that it will never be too late to buy bitcoins because the price is not the most important thing of it
Well i think its depends upon the price, and anytime the price may rise and sometimes fall so we cannot blame anyone to ask this kind of question. I believe that bitcoin right now is in the falling status which means a big opportunity for us to buy more and hold for us to gain a huge amount of profit in the near future.
It depends on the market, at the present situation, you should be buying bitcoins now, hold it for long term investment, there are some speculations that this coin will soar again in the next coming months.
