If you believe in holding it for a long term then I think the current price is the best price to buy bitcoins as very soon we may cross the price of $3000 and it may go even higher by the end of the year so at that time you can sell your coins to make some good profits in a quick time.
If more people invested their money into Bitcoin then the price of Bitcoin will go up really fast. I feel that there is not that many people invested in Bitcoin right now so the price of it is actually lower since Bitcoin is not promoted as much as it should be.
There is no doubt that bitcoin is lacking promotion at global level as its not getting support from the media and the government and if it starts getting support from the media then it will draw attention of many people who are not aware about bitcoins yet and that can take demand higher in near future.
