I think the price of cryptocurrency can all happen and it could be that the price of bitcoin in September experienced a price increase like last year because no one will know where the price of bitcoin is.
I price will go under $5800 we will know it hit bottom. But yes, we will not be sure at that time if that is the real bottom of the Bitcoin cycle or there will be another latter on. So all we will have to do is to wait for the bull market half year latter to confirm that bottom had happened. Eventually we will know. Same as we know right now that bottom of last Bitcoin cycle happened in January 2015.
