Its quite good always to be optimistic and sometimes you think of what's the worst thing that can ever happen with which one prepare well. Considering the rate at which guyz are so expectant. I thought, what if the bull refuses to run? What will guyz do? 
This can be happen. Or the bull that we expect, it may not be what we want. When we call the bull, we remember the big price increases that occurred at the end of 2017. What if the price doesn't rise so fast in the next bull season?
