I understand that I may mess up this plan in the future when one or two cash flows from multiple sources suddenly dry up. However, I have learned many things from the experiences of the people around me, including maybe some of your experiences in managing finances. This management sometimes won't go according to what we plan, but trying to avoid mistakes in the sense of managing it properly must be attempted.
So, yes.. I would not consider the likelihood that some mistakes are going to be made along the way to be deal-breakers because hopefully, you can just deal with the mistake or the ramifications of the mistake(s) once it (they) happen, yet there still is quite a bit of value in terms of trying to figure out how likely are certain mistakes to happen, and then how big would be the ramifications for each of the mistakes, because there could be ways to at least mitigate how likely it would be that the mistakes would happen and to even make it pretty unlikely that the mistakes would completely destroy you or even that that maybe you might have some mistakes that you would consider to be severe.. but they would ONLY end up dipping into your principle by 10% or 20% rather than some mistakes could end up having something like 70% to 90% dipping into your principle, so even though you may be willing to suffer some unlikely damages, it would be prudent and practical to be able to attempt to recognize the difference in the magnitude and likelihood because sometimes people engage in behavior that has decent chances of producing a 70% to 90% reckening and maybe they are calculating it as if it were only less than a 10% reckening if it were to happen... - including that frequently there are periods in the building of investments and/or principle that can take years and years and years to establish, so if you reck yourself by 70% to 90%, it's not like you can just bounce back in a period of time that is significantly shorter than how long it took you the first time, and in some cases, it is almost impossible to build the same principle at later dates because the costs have changed....
I feel obliged to recognize and understand what are the potential errors or failures so that we can minimize them properly. I realized that we can only plan everything and try to arrange it as best we can, but because I am a follower of a religion, I also have to have enough faith in things called fate or God's will. A natural disaster for example, pandemic or a larger war could blindly ruin this plan, so something like that is totally unexpected even if we have managed the plan as best we can.
Maybe we've talked too far about these plans and how to go about it, but I hope we haven't completely ignored that bitcoin is still in good reach to buy. Buy on a dip and hold would still be an option I would consider regardless of a cash reserve plan for an emergency fund, it would have to vary with the investment budget I have.
