It is pretty simple to know what will happen, price will rise, just i am afraid that after halving everone will sell their bitcoins so price might fall down, but it still will be higher than before halving
When all the people start to all their bitcoin at once or even in 1 day the price of bitcoin will drop more than it rise.
I hope that wont happen the sudden boost of seller of bitcoin in just 1 day that will really cripple bitcoin and maybe a bad thing.
