When will the bull run start?

in 2018? i've lose a lot of money through bitcoin. because price went down. when will the bull run start and i regain my money?
As soon as there is a chance of making a decent amount of money with a huge run, right now there are so many people who would like to sell their coins at say 8-10 thousand dollar levels that if you want to go thru those prices you will be required to have a lot of money and if you want to reach to $20k once again you will have to buy a lot of bitcoin and require a capital at a size of a small nations GDP.
Hence, if that goes away and we can chip at it small by small than there is a chance but in order to get the whales on our side we need to make sure they know they will make more money if the price goes up.
