I agree with you because many investors didn't even have this in mind that, what if preventualy the dip doesn't happen or comes what should be the faith of those investors that are yet to buy aggressively all in the name of waiting for the happen, it is buying and accumulating your Bitcoin investments with DCA strategy, that always gives you the assurance of not losing all you invested on.
People usually take the wrong meaning of
"Buy the Dip and Hold". Most people think this is that they will buy when the bitcoin is at its ultimate low levels and then they will buy and hold. If you follow this, you will never be able to buy because you will keep thinking that it may dip more and you never push the buy button.
Instead, the real meaning of buying the dip is that you keep on buying every time the asset (bitcoin) dips, you have the money to buy some at cheap prices. This way, the average buying price will become very reasonable, and it can benefit you in the long run.
