For those who are still accumulating bitcoin, if they sell some of their bitcoin in order to buy back cheaper, they run the risk of not being able to buy back cheaper, so they just end up spinning their wheels or maybe just getting stuck in a waiting pattern rather than ongoingly buying, so the lose their focus and ultimately have high chances of ending up with less bitcoin than what they could have had if they had stayed focused.
exactly JJG I agree with you on one, especially those who are still in their accumulating stage which their bitcoin investment is not up to 4 years, if they sell their bitcoin with the mindset of buying back cheap it we be very difficult for them to get back on track or they might still end up buying back at a higher price, because bitcoin may not dip to the exact price they expecting to buy back, yes we know bitcoin is volatile, but people shouldn't expect bitcoin to dip to an extend of buying back cheap when you sell at a certain price.
That's it, Bitcoin is an unstable investment, and no one can predict when the price will fall. Selling a portion of our holdings in order to buy back a dip seems to be predicting that the Bitcoin price will fall more, and no one knows what will happen in the next hours. When we are not in an emergency condition where we have no other options for selling our investment, we should not sell our Bitcoin if we are making a long-term investment. We may sell now and the Bitcoin price continues to rise, so it is better to refuse to sell and continue buying high and selling higher in the future, bright days are on the way.
