I also don't think any sane person would sell their saved bitcoins at this time when everyone is seeing how high the price of bitcoin is now and how much higher it can go. I regret that six months ago I sold some of my bitcoins, now I wish I hadn't sold them.
It is said that a man learns from his past mistakes, so I think no one should make this mistake now, if they have old bitcoins they bought when the market was very much down, they should save them for at least six months or a year from this point because we are yet to witness the actual bull run which generally occurs after the halving event in every Bitcoin cycle.
no one can predict with certainty how much the price of bitcoin will rise when and after the halving occurs. Therefore, become a player in it so you can feel how valuable the bitcoins you have are. and even though bitcoin has experienced a decline, don't sell this very valuable asset, because there are still many people out there who want bitcoin at an even cheaper price even though that will never be possible.
What we might not understand about the bull market is that it is not certain the actual time the price of Bitcoin is going to skyrocket that is why we are left with puzzle of trying to buy as much as we can so we can make money from when the price of Bitcoin skyrocket. The bull market is going to come and continue but we are left with the confidence to buy and hold. If we want to buy and make money we would be ready to avoid some unnecessary buying because it looks like the price of Bitcoin might still go down which will be a perfect opportunity for this that want to buy and hold.
