Every investor applies any strategy, it's actually okay depending on each individual and according to their comfort. However, if you want to invest in the long term using the DCA strategy, namely by buying every week or every month according to your budget and Hold this is the right strategy. Regardless of whether the price of bitcoin goes up or down, we still do DCA every week or month. That way we will feel and be able to enjoy this strategy as you said. If you wait for the price to drop to do DCA, you are afraid that you will regret it later, because the price of bitcoin cannot be predicted when it will drop.
I myself am sure that the DCA strategy will make me successful in the future because I have a motto "In Bitcoin We Trust" with a bitcoin supply of only 21 million, I have a view and belief that one day bitcoin will become the most expensive asset I have.
Investors should choose strategy that works for them. DCA is good way to invest in Bitcoin for long term. Buy Bitcoin regularly no matter price to reduce risks. Stick to plan and do not try to guess when price will go down. Bitcoin price is unpredictable so it is hard to know when it will drop. I also believe just like you in Bitcoin future because there is only 21 million of it and I think it will become more valuable over time. The phrase In Bitcoin We Trust shows strong belief in its success.
