If you see a BTC trend then holding is better. But everyone has their own opinion.
If I choose three options divide between BTC, USD and altcoins. I use this for backup because it could be wrong predictions for what I have.
Several times I have sold some of my BTC out of necessity. Otherwise I will store and multiply BTC.
I am not selling firstly at lesser price, secondly since I am a long term investor so such falls does not shakes me actually. As well, if have some funds or can manage to save anything extra for that month then during dips I invest more in bitcoin as it will always have a good bounce back in future.
We have our own strategy for bitcoin. Maybe some of us are still holding bitcoin until now and buying bitcoin when the price is at the dip. But the other will buy and sell bitcoin and take profit and save the profit for their needs. As long as we know what we should do and save some bitcoin while we are trying to cover our daily needs, that will be no problem. We sell bitcoin whenever we want and also hold bitcoin for our future.
As long as you are capable of holding your bitcoin without ffecting your daily budget that still good, after that huge last time high
the chance to hit that back is still very possible.
At this moment, while up and down is taking place. Long term believers will buy the dip and hold for more bagholds.
Those people are already making a big profit from bitcoin because the price now increases to $39k, although the price now is down for a bit. It gives them the courage to still hold their bitcoin from a few weeks ago when the bitcoin price is down deeper. In the future, we will see bitcoin prices will increase higher more than today, and if we can have many bitcoins from the waiting time, we will make a big profit in the future.
