Nobody knows my friend. But if you scan the topics most people believe the bottom lies somewhere between 2300 USD and 2700 USD.
You will have to find out for yourself if you are willing to take the risk of buying at the $ 3K mark. If you are in for a long term investment personally I don't think you will regret buying now. If you are aiming for the absolute bottom then at least wait what the weekend will bring you.
Good luck!
It is a subjective question, since no one really knows the absolute ceiling and bottom of bitcoin's price value. All we have is speculations, and legitimate news that may affect the movement in its price. Base on how we read the fluctuations, we roll the dice of our investment. But, if we are in a long term investment, better to review and monitor the previous price record as guide.
