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?
The same thing happened during last bear market. patience is the key. I hope you invested only what you can forget for a few years. I expect a big price point for bitcoin somewhere around 2022. Not so much for majority of the altcoins, so be careful when you pick them. Take gains that you can.
