The most important factor should be supply and demand. Only when demand is more, the value of bitcoin will be greater.
The current market indicates that the demand of people is relatively good that is why the price is 6.3k dollar from three days it is stable here but this price is still low and is inside the circle of common people so they will achieve and afford it easily.
This is a type of benefit too if people invest with huge amount and get coins in large quantity. These big investments will make the Bitcoin to go high and it may jump in the upcoming days.
