Every Bitcoin investor aims profit and in order to achieve that they would want Bitcoin to drop so they can purchase more and then want it to rise so they can sell
Investors that achieve profits for investment are the Investors that invest in bitcoin and forget about the investment for long run, not necessarily the Investors that focuses on when price of bitcoin will fall before they invest, that is why during the time of investing in bitcoin nobody will tell you that this is the perfect time for someone to invest that is the best time, and secondly when you invest in bitcoin you will not be hoping to make profit same time because it may fall or rise. What I notice is that Bitcoin can rise at any point in time either you purchase when the price is low or when the price is high.
