A mistake that we new investors make is not setting our target. Determining the target is very important, in a word, the investment target can be considered as the structure or design of a building before it is constructed. Just as a building without a design is not possible precisely because of it, it is impossible to sustain an investment without a specific goal in a long-term investment plan.
I believe that all of us have their own targets but the problem starts when we actually hit our target and we don't comply and follow the plan that we've setup. And the reason for that is the nature of human about greediness. We all want to see more, the better and higher price that's why even if we hit the target, we don't obey to our own plans.
IMO, I don’t know the kind of plan you’re referring to but definitely every bitcoin investor target is getting a good portfolio. After owning the desired amount although there’s nothing like satisfied bitcoin accumulation, an investor might feel like they've gotten much but still keep accumulating that’s normal and good because there’s no limit owning bitcoin . Consistent accumulating is the best plan for me, continues accumulating after reaching an achieved target doesn’t mean greed if that’s what you’re referring to.
in most cases, the first goal of an investor is always so small and just centered at building your portfolio up to the slightest extent. In the pursuit of building Bitcoin portfolio to that extent you gain knowledge and get to set the right plans in place that can help you reach a better goal, thier is absolutely nothing that's wrong with having such a plan as an investor as long as you're not doing it at the detriment of fulfilling your core desires.
Greed is mostly applicable to altcoins that lack Future potentials and when you managed to hit some profit from it and still want to get more. For Bitcoin that's solid and less risky in terms of long term investment, reaching your goal and wanting to achieve more is not same as being greedy. Except you have a desire or an important project you've yarn to do and that is the main reason you're building your Bitcoin portfolio so you can easily achieve it, if that's the case then after reaching your goal, it is wise to carry out such project since you will certainly take out your holding at certain point and it's best you utilize it in doing the right thing and not try to reinvest it in a less profiting asset.
