Experience could be one factor to facilitate one's decision to continue holding their investment, some people are easily moved with a slight increase in the price of Bitcoin and can as well be tempted not just new investors even those who had long stayed in the system and have not yet understand the power of long term holding, so it goes more with the mindset, we are clearly expected to open our mind and accept the fact that during our Bitcoin accumulation it is expected of us to generate the mindset of long term holding and abstain from unnecessary sell pressure.
An investor should have his mind on a long term investment plan, before he venture into investing in bitcoin. He can achieve this by having a bitcoin target as his goal, so that this will keep him more focus and consistent on his bitcoin accumulation. Since he has that on his mind, he will not think of selling when he sees a little profit from the price of bitcoin, because he has not reached his bitcoin target.
But when an investor does not have a bitcoin target and he is just investing, he might be entice by the little profit that he has made in his bitcoin investment and forget that he has plans to go on a long term investment, and he will see the little profit as something big to him, which might make him sell his investment thinking that it will be easy for him to buy back, killing his long term investing goal. This is why we need to set a bitcoin target to help us achieve our long term goal, by hodling and accumulating bitcoin using DCA method, and also lump sum when we have the opportunity to buy at the dip.
Itt is highly expected as an investor but still unfortunate on how most people still deviate from the long term approach and settle down for a short term investment. Lack of patience means minimizing the amount of profit to be made from investing, it is always ideal to take the holding step and approach, many have tried the system and it worked perfectly.
Any investor who begins his accumulation without setting a budget is prone to all what you have mentioned. We should also understand that the budget being set should not be the limit to our investment, after beating the budget it is also ideal to extend further and keep accumulating but now it can be taken in a more stable manner.
