Should I wait for a dip?

I’ve been in & out of bitcoin for the last 4 years only putting a small amount in at a time & would cash out after I seen a little bit of profit sounds silly now but at the time I was young & still learning what it was all about. In the past 2 months I’ve been putting more money into it every week, little by little & I’ve seen decent growth so I’m confident on the potential. I want to put a large amount in right now but I’m deciding on if it’s smart to wait until it goes back down a couple thousand or buy all in now? Honestly opinions
