Even if you want to make quick profit, how much can you invest so soon to warrant a quick ROI? It's just a short sighted mindset that makes it look like waiting to buy at a low price is the only way that you can easily place yourself at a good profit from your investment.
If you've been investing from the start of the year till now, which other asset class has the potential of giving you the returns you should have gotten by now even if you bought the asset at a time it was even bearish? No one that has done DCA from the start of the year till now is not in a very good profit, this is just a single year consideration, what hapens if you're able to invest for the long run? For a volatile asset as Bitcoin, you can't be too accurate when it comes to timing the market and while you're hoping that it's going to get more DIP, you will eventually find out that it's getting more bullish and that you've wasted a whole bunch of time that you should have used in investing earlier. Good Profitability is one of the ultimate reasons for investing in Bitcoin and to get the best out of it, its best to have a long term plan which allows you the opportunity of investing more and putting you in a good profit.
I think you are referring to traders because they are the only ones who are always looking at the price of Bitcoin before they tend to buy. A Bitcoin investor would see every opportunity as a good entry point to invest without considering what the price is at the moment. There was a time were people were contemplating Bitcoin to be an asset for savings rather than investment. But it's clearer now to those who were still in doubt that no matter how speculative the asset has been it's worth investing for future returns. Anyone entering into Bitcoin right now should never have the intention of coming for short profits/gains. Gone are the days of quick returns, if anyone wants to succeed in Bitcoin now is either long-term or never. Of a truth, anyone who has been dcaing is on profit no matter what price they bought it when they started. Including those who start investing immediately after the halving. I can remember that period, some people were saying it was the wrong time to buy because Bitcoin had hit a new ATH. Bitcoin has proven them wrong though.
