Since we are always buying through DCA, it will be difficult to always determine our entry point. For me the holding period is the main priority in this case. It will be foolishness for me that doesn't have up to one bitcoin to compare my profitability with someone who have up to one bitcoin or more. But if someone who has up to a bitcoin sell of early and I continue holding my bitcoin for many years, there is every possibility that my profit will get to his level when he sold of or more, because we don't know the amount that bitcoin will get to in the future.
Actually an investor who is slowly coming up using DCA method to accumulate Bitcoin shouldn't compare themselves or trying to compete with those that has already started investing on Bitcoin for long because always trying to get an amount of investment other investors have could lead to aggressive investment were as you will put everything you have just to remain on the competitive trends, although there is no harm trying to accumulate as many Bitcoin as you can but trying to compete or reach out to other people amount of investment is not wise because it could lead to aggressive investment which could sometimes cause by fear of losing out, so perhaps in as much as DCA method takes a while before getting a reasonable amount of Bitcoin but is actually the best and you would be surprised with the amount of Bitcoin you will realize from ten years and above.
They should not compare any individual success or activity done since each people have their own timeline on when they starting up their journey to hodl. If they see those people doing good on what they are currently doing then everything is fine on their end and we can just look after them then try to get inspired to get more better result to. But they must not forget that they must do better for theirselves since no one can help them to decide what strategy to use,how much they are willing to spend and how long the timeline they set before they decide on when to execute everything according to their plans.
Bitcoin is just there and for sure it will stay for long time since many people already know its existence and provably for more years we can see a lot of success including more price rise especially that we know there's only limited supply for it then there's a lot more people coming to grab some because they see how good bitcoin as an asset or investment.
