Personally, I suggest that beginners to bitcoin can come in with 5% to 25% of their income into bitcoin, yet they surely have to figure out if even my own recommended range works (and is appropriate) for their personal circumstances, and in the end each person is responsible for his own choices of both whether to invest in bitcoin and how much, and surely many of us suggest to get off zero and to get into some kind of a beginning range (such as 5% to 25%), yet there still is an overwhelming majority of normies who are still stuck at either zero or very low levels of allocations to bitcoin.
You've made a valid point, and this leads to my question. Do you think some of these normies don't have that financial capability to allocate from the little they have, or they just don't know how to make plans and allocations?.
Now, my reason for asking this is that, in most cases, we come across people who finds it difficult to invest from what they have, because it is considered very little. And even though these set of people are opportune to get more income (maybe through salary increase, as a result of promotion), or other means, they still find it difficult to pull out a certain amount for investment, probably because they feel that an increase in income, also means an increase in expenses, which IMO, is a bad behavior to managing finance.

Before doing steps like that and DCA or buy in lumps, a person should consider all the risks, analyze a big chunk of info needed, and keep acting toward the goals in his mind.
Of course, DCA demands consistency and focus, but I don't think the whole analysis thing is very important, besides there is no risk in investing for long, as long as your accumulation is intact and safe, because security matters alot for a long term journey.
