It is better not to sell Bitcoin thinking about your own profit. We should think about how to hold Bitcoin in the long term. How to invest and take Bitcoin forward. We should not sell it immediately, thinking that the price will fluctuate in the market.
Why must you sell when you know you are not going to earn big income that will make you happy, every holder know the exactly price bitcoin will hit before they will visit the market to know what to do either to sell or continue holding for higher price, because they know the price they bought their bitcoin from that will make them to decide positive, those that sell their bitcoin immediately they bought from the market will not earn huge income compared to those that bought and hold more than five years before trading in the market, for those that want to buy bitcoin to add to the ones they are holding, I think the price has decrease for them to buy and continue holding to see another all time high (ATH) soon.
You are sounding like a trader because an investor doesn't care about the price they bought Bitcoin, the priority is on achieving or getting to the overaccumulation stage and this is a kind of relaxation or dew point for an investor because at this point they don't need to over stress themselves because the goal has been achieved and this is also a stage one can decide to diversify if they are interested. Buying and selling immediately is trading and it is very risky because Bitcoin is a volatile asset and you can not easily or certainly predict the what will happen in the next minute.
