When this thread was opened (seven months ago) the price was below $600 and it was undoubtedly a good time to buy more coins. But at this time I am not so sure that it could be a good idea, because we are closer of the record high and at this point none can affirm with certainty what will happen next.
It is in fact, the general impression of traders that tilts the market to the side that it goes, so now the majority of traders are of the impression that bitcoin is already overpriced, so buying it now would not be a very good business decision even though the project for bitcoin in 2017, is that the $2500 price mark would be hit.
Like it has been said over and over again, the way to profit in trading is by buying low and selling high. If you have been observing the market keenly, you would have noticed as a result of the cyclic nature of the market, that there will always be another opportunity to buy low.
The opportunity to buy low is today. The price has been playing around 900$-950$. There has been a recent dump/panic dump that has happened. Some people would doubt that it's a good time to buy right now since it's $900 and $900 is a big amount of money to most. That's the same thing people back then was thinking. Even the OP of this thread has made this thread because he was doubtful with the $600 price. Now, he's enjoying his profits.

The price right now is overpriced only to people that wants to cash out in a year or two. But for someone that wants to invest bitcoins and then cash out after a couple of decades, the price of bitcoins right now is soooooo cheap (and I can't even emphasize that even more). Bitcoin is still in the beginning phase and this price will be something people in the future would think as "really really cheap" just like how we see the price of the past (a couple of dollar for a bitcoin) as really really cheap.
