As a volatile coin, there's no need to wait or be expectant of a particular price before buying, the future of Bitcoin is less predictable that's why starting at any entry then be consistent with the DCA is far more better, it helps avoid wrong timing of the market and keep investors in an advantage of buying different dips.
This is true, because no one is certain or precise when predicting prices. So it's better to continue without expecting the price to match our desires. We don't know what will happen to the market price in the future there could be an increase or vice versa. The most important thing is that we simply act according to our desires, so we don't focus solely on the price direction that has become our reason or mindset, always expecting a decrease based on predictions which are uncertain events that will occur according to our expectations.
What helps us invest in Bitcoin is simply having a consistent attitude. We don't need to act without this attitude. A very disciplined and consistent approach can open up opportunities for us to profit from Bitcoin investing.
I believe most people where even waiting for Bitcoin to fall as low as $50k before buying but most of them would be currently disappointed that the market is trying to recover to $70k, that's how unpredictable Bitcoin can be and why being consistent with the DCA is important.
Many are disappointed rather than waiting for the price to drop as you mentioned. Those who want a price drop before buying are only beginners who sometimes have very limited knowledge of how to buy Bitcoin at $70,000, for example. I think it's inappropriate for them to wait until they want to buy Bitcoin sometimes just to get a large amount. If they knew how they wouldn't wait so long for the desired time. That's what's happening right now for beginners who want what they think while for those who have been investing for years the idea they want is certainly not one that can be relied upon because their basic goal is to carry out Bitcoin investment unprofessionally.
