Of course, past performance does not guarantee future results, so you just do your best.. and sometimes it can be o.k. to build up a separate fund that you would be able to use for buying on dips, even if you might ONLY be setting aside a few dollars every week for such potential purposes, and frequently I think that $10 per week is very small, yet I know that some members in some parts of the world feel that they can ONLY do $10 per month, and so doing $10 per week, you are investing 4 times more than they are.. and sometimes there could be some ways to both invest into bitcoin regularly and to build up a side fund that you would use for buying on dips.. and really my example 8 is stemming from the hypothetical income and expenses that I described to exist in example 1 .
Yeah you are right past performance doesn't guarantee future results but it only serve as a roadmap that will guide him through his investment decisions and the negative or positive things that could happen if taking a certain decisions and how he can avert it.
Actually having a separate funds is a very nice idea because if our intention is to target both the DCA accumulation and buying when the price is dip, so perhaps we could structure two ways of accumulation first keeping or budgeting a particular fund for regularly DCA accumulation and secondly by keeping a fund to accumulate Bitcoin when it dips. Perhaps just like your explanation on the example 8, there is every need to have a lum sum method if we are using DCA strategy because it will always enable us to utilize every opportunity given to us when the price is dip but although it all depends on the financial strength of the investor.
