Right now is the worst possible time to sell any of your coins. The prices are so low that at any point over the last year it would have been better to sell than now. I think that most longterm abf HODL investors are aware of that and are not considering selling any of their crypto coins. Short term volatility should have never any influence on our decision making, it's better to hold for another few tears than to sell now. For a trader things might look differently, he more concerned with shortterm profit.
Even though there are still plenty of HODL investors I don't think the bitcoin price is going to rise at the end of the year. The demand for cryptos is not strong at the moment, people are trying up get by with the higher living expenses and with Christmas around the corner there is not much free capital to invest left. The good thing of longterm investors not selling their coins is that the price is not falling further. We have to wait for 2023 for prices to recover.
