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.
Even a guy investing
$10 per week since October 1, 2013 might feel that he does not have enough BTC, but he is in a real good place, since he had invested nearly $5.7k and he has nearly 7.1 BTC.
And the guy investing $100 per week over the last 6 years does not have as many BTC as the guy who started in 2016, but he is in a better position for having had invested into BTC, and
he invested $31.4k and he has nearly 2.54 BTC.. still not a bad place to be, but he might feel that he does not have enough, and he likely is not going to catch up to the guy who started in 2013 with only $10 per week.
No one can really tell us where we are going and how long it might take for any of us to feel satisfied with our BTC investment, even thought there surely remains quite a bit of potential value in getting started sooner rather than later, and with the passage of time, BTC's investment thesis is not getting any weaker.
