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!
This is the right time for you to buy bitcoin because look at the price. Even if it is so high that you cant afford its too worth it. And when you already bought bitcoin. Maybe you can invest it too make it grow and to earn money.
