If it was like the last one, it seemed to have about 6 or 7 cycles bull correction bull etc.
As I'm being part of crypto currency community way back 2017, no one can determine or predict the possible outcome. As you want to know when the bull run will over, well its just a matter of time when the investor or the users will continue to support the demand of crypto currency community. Even how long experience we have only time can tell when it will last but for now we cherish the moment since it still demand in the world of crypto currency.
