It all depends on the individual,it’s a choice to make whether to adopt the DCA strategy or buying the dip.You not buying the dip doesn’t make others who are buying look unserious,they all have their personal or financial reasons for not adopting the DCA strategy.Every strategy has an advantage and a disadvantage,the reason why buying the dip may seem delaying or unserious is the fact you might have the available resources to start and you can’t start all because you’re waiting for the dip,then when the dip finally comes you may be in lack of resources that is why it’s important to start with the DCA strategy.But note,bitcoin won’t drop drastically to the point where it was created that is one thing to note so if you’re waiting for the dip you need to target a particular price.
I believe there's really this psychological aspect of investing, which people sometimes forget when they're making their decisions. In theory, waiting for a dip sounds easy, but not many investors are able to do that when the dip actually arrives. When the market prices begin to drop too rapidly, fear creeps in and they begin to think that the price will even drop more and they keep waiting and waiting and still end up missing out.
That's why consistency is so important, it takes out a lot of emotions and guessing from the process. While it may be wise to have some spare cash at hand to make big corrections, but it is also important to be patient and disciplined enough so that when the market experiences a major drop, you are ready and confident enough to make a purchase. The most important thing is the strategy that an investor can follow and stick to it through various market conditions.
