Well this issue has been delt with by JJG so it's pointless repeating it again rather we should focus more on using the strategy that suit us best to accumulate more Bitcoin and hold it for a long period of time in order to get a high percentage of it which is the reason why we are here. And the best way to keep our investment going even when we want to sell is not sell the whole... But rather selling a little of it will be great so as to keep your investment and also buying or DCAing to meet up with what has been taken off from the investment but most people don't know this, that is why they find it difficult sometimes to invest again after they have sold everything.
A new investor should not think of selling any of his bitcoin investment during his accumulation phase because if he has the mentality of selling some part of his bitcoin investment during his way up, it will deprive him from reaching his bitcoin target at the right time. It can also become a practice for him and that shows that he has become a trader instead of an investor. This is why he only needs to focus on buy buy buy and not sell sell sell to build up his bitcoin portfolio overtime.
This is why the proper plan and preparations should be put in place before starting your bitcoin investment journey so that you don't sell part of your bitcoin until you have more than enough of bitcoin in your possession. Using the right discretionary income to DCA regularly every week or month for 4-10 years and above, also setting up an emergency funds for 3-6 months, reserve funds, float and buying aggressively with DCA without overdoing it will safe you from selling your bitcoin investment when it is not your heart desire.
Its pointless to think about long term if they have this thoughts to sell early their bitcoin since they fall into trading with that situation. If they became greedy when seeing some good profits temporarily show up then most likely they would fail on their long term investment plans. This also show that they are not really committed doing long term investment since they are affected on the price changes in the market. We should focus on things that can give us more good result rather than thinking about any short term which for sure that we are the one who will suffer. To avoid that, they better have good assessment on each action they made so those people could able to think about what's more better things to do and avoid committing any bad decision for everything they try to do.
Preparation is always important and consistency since if we have at least these two traits then provably that accumulation will be smooth in our side.
