Where it's really wrong waiting for the dip before buying is when you have no Bitcoin or less stash of Bitcoin in your possession, at that instant, you don't wait, you just buy it regardless of it current price in other to increase your stash as much as possible, then if their is a dip in the market, you might decide to buy aggressively only if you have the financial leverage to do so, but waiting as a low or no coiner is actually a terrible mistake in my own opinion.
I disagree with you here. You will be making a mistake if you wait to by the dip when you don't have any strategy you are using to accumulate. Buying on dips should be a secondary/temporal method of accumulating Bitcoin. The primary method should be one that you are using to accumulate Bitcoin on a steady till you reach your accumulation goal.
If you look at my full write up very well, I said that it's very important you buy and accumulate Bitcoin regardless of it price especially when you have less or no stash at all, but if you have gotten close to the peak of your accumulation journey, you might decide to wait for a dip before buying because you have the leverage to do so, and you know why? Because time is on your side unlike someone that is a low or no coiner.
But take note that it's not compulsory at all, it all depends on the person if he wants to leverage such a situation to his own benefits, because I know that not everyone that is closed to the end of their accumulation will act in such a manner.
