I think many people would be already buying when it hits above 25000 dollars and above 30000 dollars it would already hit news.
Honestly I wouldn't buy huge amount of Bitcoin yet I think we are still at too early phase for next halving. Although breaking limits can be convincing to at least buy some for quick gains. Like going up from 22000 to 25000. It would be worth. But I tend to hodl. I prefer long term big gains.
When bitcoin hits 25k or 30k although can't say for sure it's a sign of real bulls coming but there will be a lot of Fomo people buying at this price because every time the market moves too fast, everyone People will always assume that bear season is over and bull season is coming. For those who bought at a lower price, I don't think they will be in a hurry to sell their bitcoins because they also think bitcoin will go up in price.
In general, depending on each person's view of the market, there will be people who take profits waiting to buy back, there will be people who think that bitcoin will not fall anymore and the buying opportunity is no longer available, so they will continue to hold until it surpasses ATH.
