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.
Plus it's also very important for the newbies to know that it's better to concentrate all of their capital on one asset that's NEVER going to go away, and that's Bitcoin. Those "traders" who buy and sell different altcoins/shitcoins will definitely have a harder time finding which narrative is the current one to "trade" because the market this cycle is VERY dispersed. There's simply more and more cryptocurrencies and tokens listed in more and more exchanges, centralized and decentralized, under different sectors.
Because it is so dispersed, I believe it might make many of them surge in smaller and shorter durations.
