None knows this for sure. I do believe the next bullish season will be coming maybe after bitcoin will have done another hardfork but again there;s no guarantee when that will be happening. People must wait even longer when the bullish trend already gone. Remember that the bullish trend already gone at least 2 years and i think that if the bearish trend will have the same cycle like that. I would not be surprised if there will be more dump soon.
Expecting bullish trend to come as soon as possible was not even rational
