Investment is not to trouble ourselves if indeed we are eventually affected by inflation and the worst possibility is that we cannot continue while the DCA is done then I think it will not be a problem because we invest not to trouble ourselves and remember this investment is only as a support for us to enjoy the old age that we hope to be beautiful.
This is the reason why one have to increase his emergency funds and reduce the amount that he is using for DCA. All these is because the person failed to prepare properly before starting his bitcoin accumulation. If not one should also consider some unforseen challenges when investing and prepare funds for that so that you don't end up selling your bitcoin when it isn't your will.
Rather than in the end this will hamper our needs by forcing investment which of course will also not be able to be done properly then I think in this case fulfil the needs of life that we will do first.
If necessary, we can also sell some of the investments that we have built before (if they are profitable) to cover the needs we have so that we can be free from the inflation we receive.
Yea, when we fail to prepare well, there will be no other option that to sell the bitcoin to use to take care of important responsibilities. This why one needs more than one source of income so that no matter the level of inflation it would't affect you from accumulating,but if it does affect you from accumulate, you can stop for a while before things put themselves in shape, rather than selling the little that you have.
As nothing is actually ever simple in this world to do especially when it comes to field of financial stability same thing applies to actually successful holding your Bitcoin and it's another case if you are accumulating through DCA, why? Well because it's not an easy task and most people actually just give up at the long run of it because of so many reasons and here are some.
---lack of discipline
---wrong financial income or none at all
---No proper planning
--- procrastination
--- impatient
Before anyone can properly practice DCA and still hold on to their investment for a long period these certain barriers are to be broken.
It seems that you are getting DCA mixed up with other kinds of investing (such as lump sum investing), because DCA overcomes each of those items in your list because once you get started, then DCA makes it easy to overcome each of the items, because all you need to do is pick an amount.. $100 per week set it and forget it..... and if you think that $100 per week would cramp your lifestyle too much, a different amount could be chosen.
Of course, there is a need to both set up the DCA and there is a need to figure out what the amount is going to be, but there are ways to do minimal levels of work.. and then just let the investment strategy ride for several years, and sure maybe after a few years, there might be some needs to look at how the investment is doing and then to reassess whether further actions might be needed, and if the amount is starting to add up to a lot, then having stake in the game may well motivate further activism in regards to the investment.
I agree with you, DCA method has eliminate those reason that was mentioned by @Danny001, because you have planned to use a certain amount to DCA based on you cash inflow and this makes it a proper plan and discipline on your investing strategy. Someone that procastinate will never DCA amd wouldn't be able to achieve his goal when he has the money. The people that can procastinate are those that think they are wise enough to time the dip in bitcoin price or those that want to buy in lump sum. It is a good amount of emergency funds that is needed to enable you with you regular DCA method and not as mentione above ny Danny001
