Indeed, no one can know exactly when the price will skyrocket again, it's always depends on the sell/buy orders made each day and also it depends on the daily use of bitcoin and the manipulation of whales as well as the news about cryptocurrencies as legalize/legalize it in some countries or news about ban it, that all can effects bitcoin's price and can make it decrease/increase a lot, but sooner or later bitcoin's price will increase, we just need to patient and wait for the good news.
