It should be noted that I am not saying that buying strategies are not important. However, I am saying that all buying strategies are the same (good) if the funds used to invest in bitcoin are discretionary income.
On the contrary not all buying strategy are good, you spoke of lump sum strategy and DCA accumulating strategy, but you never spoke of dip buying, and I can confidently say that those investors that focus only on dip buying aren't doing it the right way, because by waiting for the dip they are going to miss a whole lot of buying opportunities that may present itself in the market, so it's not a good strategy.
The best way to invest is to use either the DCA accumulating strategy or the lumps sum strategy, then if their is a dip in the market, you may decide to buy aggressively then, only if you have the reserve funds to do so, but waiting for the dip only as a strategy is a terrible way to invest in Bitcoin.
Fair enough, i quite agree with you when you say that those investors who focus only on dip buying aren’t doing it the right way, but that doesn’t mean that it is a bad idea to buy in the dip especially when the opportunity to do so presents itself. buying in the dip is not overly a bad market buying, but where it is bad is when an investor whose initial strategy is on the long term goal of accumulating and holding always wait until When it is dip before he or she starts accumulating. Don’t get me wrong, I’m not in support of waiting to buy only in the dip, it’s just that I’m not writing off dip buying when the opportunity presents itself. Which ever strategy employed by an investor, the most important thing is that it is pertinent you invest with not more than what you can’t afford to lose, and that’s why is advisable to always invest with your discretionary income. And as long as you’re accumulating and hold for the long term goal of investing, without trading for a quick gains, or you’re not panicking to sell whenever you notice a downturn in the market, and also being consistent with your accumulation and hold for the long term goal, then I think you’re on the right track.
