I personally don't have a set target for the number of Bitcoin that I want to accumulate into the future, because I don't want to put myself into unnecessary pressures to achieve the goal by all means. Although there's nothing wrong with setting a soft target for yourself into the future, perhaps in 10 years time to achieve a reasonable amount of Bitcoin but there's no need to over labor yourself or deny yourself of basic needs that are essential to live a healthy lifestyle because you want to accumulate 1 or 2 Bitcoin within the timeframe.
You are getting it twisted, setting a target doesn't mean that you should not take care of your basic needs or monthly expenses neither deprive yourself from other important things that must be done. Setting a target will only enable you stay focus and work towards it with all commitments and determination because you have a goal to achieve. For instance, you will be careful with the way you spend your extra funds and cut down expenses on stuffs that you can do without. For instance, drinking two bottles of beer every week or the money that you put use to gamble every week will be channel into accumulating more bitcoin apart from your DCA.
Also, whenever you have extra funds that you don't expect or plans for, it will make you think of buying bitcoin with it right away because you don't want the money to be used for something that will not be beneficial to you in future. The investor can easily lump sum happily with such funds because he has the zeal and passion to reach his bitcoin target.
Bitcoin investment does not need pressure to invest because it's a long term process, otherwise, you might end up selling your bitcoin when there is too much pressure on your finance because you are doing it the wrong way. Bitcoin investment should be done the right way for success in future.
If you carefully go through my post, you'll notice that I never mentioned that setting targets for your Bitcoin investment is a bad thing or that it can prevent you from taking care of your basic needs. My focus is that some people can set unrealistic targets and in the process of achieving the set goal of meeting their aim, they overlook their well being. So what works personally for me is that my focus is on making sure that I'm removing the percentage from my income into my DCA strategy for buying Bitcoin.
I personally don't bother so much about how much Bitcoin that I want to own in the next 10 to 20 years, what is important for me is being prudent with my expenditures every month so that I won't miss out on accumulating my bag. As my income is increasing so also I'll be increasing the amount that I set aside for accumulating Bitcoin. But what doesn't work for me might work for another person, it's the end that justifies the means. Whether your motivation is to focus your set target for a perticular amount in the future or you're more concerned about not missing out to buy now, the important thing is for you not to relent or stop your accumulation and hodling.
