I agree, that this thread talks a lot about investing in the long term in bitcoin and long-term investment certainly will not require too much analysis.
Investors don't need to deep dively into technical analysis but simplify it too much possibly results in careless in people. To succeed in investment, people must spend enough time, and decent efforts for searching and learning very basics of Bitcoin as well as vital principles in capital management for individual finance and investment. If they don't have enough dedication to do those things properly, their investment adventure can be very unsmooth and they even end with loss.
And for beginners, my advice is, just do DCA, so don't worry too much and just enjoy the process.
DCA is a good strategy for investors who are either newbies or senior but as I emphasize above about vital role of financial and capital management before you start and during your investment adventure.
