everyone will certainly not know for sure when the market will recover again, because here we can only predict it, the market will suddenly be recovering and it may even take a little longer, and many people predict that by the end of 2018 the prices of bitcoins and other altcoins will again grow higher in price, as has happened in the past years, but that is not certain, so we must have our own predictions and speculations about when bitcoin and other altcoins will rise again.
I think we can not give a forecast in any case. The market will turn when the whales need it. While the market is manageable - the forecasts are useless.
