That is exactly how it is suppose to be, holding for a long period of time before having a thought of selling but it appears that some people have made up their mind to buy and sell whenever there is a little profit and hoping to buy back when the price drop although it may look like a strategy for them but trust me it is not the best approach to Bitcoin investment and most of these people don't use what they can afford to let go that is why when they buy at a certain price they will have a target where they want the price to reach before they will sell and whenever this doesn't go as planned and they used what they can not afford to let, they will sell even in loss and this means that you are going backward instead of forward.
Mate I can categorically tell you that any investor that buy and sell at a time when there is upsurge or appreciation of Bitcoin price should be considered as a full time trader, there's is no other adjective to qualify such individual except them being trader which are quick profit chasers in reality, buddy on a general note, when an investor starts deviating from the concept of Bitcoin investment which is long-term then such investor can be attributed to be a quick money chaser.
A long term investor can never think of selling to buy again when the price drops, this can only be done by a Short timer, a long term investor have a target and his or her target is to keep acumulating Bitcoin as much as possible consistently and hodl for a long-term.
Buddy whats even the need for someone to have a target of where he or she wants the price of Bitcoin to reach in a short while, I can remember the time every bitcoiners was waiting for the milestone of $100k, it took time for sucb price to be actualized, so as a bitcoiner, perseverance, consistency and steadfastness remains the approach for achieving your goal, buddy using what you can afford at the early stage of your investment is good but remaining at that stage when you've known the dos and donts of the said investment isnt nice, though your source of income matters too, that's why it is advisable for every investor to seek for more source of income to enable them upgrade their acumulation and hodl for a long-term easily without stress or pressure of any kind.
