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.

So if you feel the need to enter the market, consider buying in step by step. However remember that this may be beginning of a long term bear market, so while I personally am fairly positive that we're going to recover in a few weeks it may take years until you're able to turn an actual profit.
