Expect the unexpected and that way you won't get surpised or disappinted.

Another thing I would suggest you is not to obsess too much about bitcoin price and how muh it could go up and down. I mean, I can understand if this is your first bull run as we all went through that phas,e but sooner you get that kind of mindset behind you and focus on hold&acquiring more without you will feel much more relax. Especially when bear market comes.
