You are making sense, Dips are inevitable in the market and some investors are not ready to invest when the price of Bitcoin is stable, for example how we know the stability price of Bitcoin to range between $70k and above, so a few investors might actually want to see the price go below before they invest but from another view it is not always efficient most especially when the Dip the investor have in mind is far more below the stable price, he may keep on waiting for a longer time untill the price begin to surge further instead of declining to his expectations and will be left with no other option than to buy higher than expected.
