I think almost all investors have their own selling targets. This means that everyone who invests in Bitcoin will have a price target to sell in future. It will Only a few will continue accumulating without any plan to sell at a specific price target. However, I believe a time will come when even those who initially did not have a selling target will start selling because we can't hold it forever. Our old age might also lead us to sell. It is also possible that some people may choose not to sell, allowing their children to inherit their Bitcoin investments instead.
Unfortunately after purchasing bitcoin or altcoin all investor have their own target for selling their cryptocurrency assets depend on kinds coins holding, indeed make investment in bitcoin they set up how much bitcoin price increasing to sell and how long with their bitcoin keep holding. Some investors get stable financial maybe free for long term holding and just selling if any emergency fund needed to recovery with their business but during not any urgent keep hold their bitcoin until reach most expensive price.
I believe the holder will enjoy the profitable in the future if holding bitcoin but if keep calm down and not get panic when bitcoin have bad news, its not easy how to control any investor get panic selling their bitcoin assets when any bad news and forget with their target for holding bitcoin with long term target or price raise of bitcoin have to sell.
Need change with mindset and panic moment when bitcoin crashing to lower price, keep patience and always remember with target how much percent for bitcoin have to sell.
