I think it is not necessary to buy bitcoin everyday specially in times of bull season, because it is so risky to buy btc during bull season, the best time to buy bitcoin is during the dip but not everyday we need to make a proper timing to buy because it involves capital so we need to be careful to avoid loss.
It's not compulsory to buy Bitcoin at all; neither is it a must to even buy in the dip, but to me it's important and beneficial to the buyer if he or she can buy whatever time they want to buy, be it in the dip or during bull season. It all depends on when the buyer's money is readily available; as such, there is no reason to waste any time.
