What's really important to consider by people is they apply all methods they learn here and could able to continue their accumulation at whatever cost since they could still earn in future. There's a lot of chance for people to gain so continue to accumulate and do those helpful methods what mentioned here. But people should know that there's nothing wrong for thinking about selling their profits since its up for the person if they are fine with current profit they get and what's more important is there's still a balance left for holding which they can able to use for next round of their long term journey.
Though everyone has there end point target, but that doesn't mean people should just sell off along the line while the goal has not been achieved. That's while investment differs in time Horizon, if a person decide to invest in bitcoin, he may chose an investment package of either a minimum of 5-10years and also a maximum of 20-30years. so if the person who choses a 5-10years investment package sell of his HODLing during 2 or 3 years interval, surely the person has no goal or the person is inpatient. Though if he sell his bitcoin earlier before the predicted time, the reason for selling it may be for a serious issues but I don't see need because before starting the accumulation process it is advice that people should set aside emergency fund and reserved so Incase issues rises it will not affect our bitcoin HODLings. Selling it is surely an act of inpatient or for gambling porpos.
