This is why you hodl and don't attempt to day trade. Its likely that the price will never dip down to what you sold your coins for. You may end up having FOMO and buy for a much higher price. If you are serious about making money I wouldn't wait much longer, a lot of institutional investors are dipping their toes in crypto now.
True, it took quite a while for bitcoin to dip to 3k. Since the rise still seem to be gradual compared to 2017, I'm also not expecting any sudden drop soon.
HODL really seem to be the best strategy for now while we wait for how high up the prices will soar.
