I think for now is better to invest. The dip is so deep. The prices as expected will rise on the 3rd quarter of this year.
I dont think so that there is anything profitable which you can have while waiting for little longer and that not to go for investing of the money. If you are in a position that you can take this step of investing of the money, then you must go for it and that too without thinking much over it. Buy the coins which you think can help you in making more money and that keep holding those coins.
