Yes, and  I did several times.
Not all are holding anyway as that was their choice nor I should have to hold forever but something to enjoy while I could still use it to buy stuff.
Maybe you are right that if everyone will hold it makes the price of Bitcoin dump but this had never happened in real life because not all are holding. Buying and selling is the nature of this market, might these people buy now and possibly sell it by tomorrow, that can be happening depending on their decision and the reason why they are here in crypto.
