I agree with some opinions about DCA where there is nothing you need to think about other than your focus on buying Bitcoin on an ongoing basis where you buy BTC regularly every week. No need to do it aggressively but just adjust it to the same budget as you did for your first purchase. With DCA, you don't need to worry about the price going down because while you are still in the accumulation stage, the price drop is a big enough opportunity to continue buying Bitcoin.

You can focus on investment targets every year because I have implemented this where the first year goes quite smoothly and that way we can focus on the following year. Bitcoin can change your life if you are smart in investing in Bitcoin. The meaning of being smart is holding it for the long term without being burdened by thoughts that haunt you.
