No one can be sure when the bullrun will happen, it could be tomorrow, or next year, or 2 years from now, no one can be sure when it will happen. But what is certain is that it will happen, and if we want to take advantage of the momentum there is no other choice but to prepare ourselves from the beginning to welcome it - either with DCA or accumulation - someone can potentially profit by using that method. Or lump sum, it can also be used by investors if they want to buy Bitcoin in large quantities and want to hold it until the bullrun later.
