Let's be honest
A person who's only concerned about the dip should be considered a trader
An investor doesn't just wait for the dip
They have a target and a plan in making their investment.
Pick a project(Bitcoin) you trust with a great future and accumulate rather than waiting for dip to sell the top.
Yes once the dip comes buy not because is a dip but an opportunity to get cheaper especially if you have the spare funds. 

A person that chase the dip would get anxious if they buy the dip and more dips comes popping some might choose to quickly sell to buy cheaper especially when bloggers start posting what they know nothing about.
Alas after selling it might be too late.
Wishing for a dip, doesn't mean it would come
Try to DCA smartly. Especially if you a nocoiner or haven't accumulated enough.
