well, in this context of buying the DIP, Thier is nothing much about time wasted. Whatever time you decide to buy is actually a good time as long you're willing to wait long enough. Like boss JJG said earlier, the better time to buy is yesterday but we know that's already gone so the best time to buy is definitely today. Even if in the next months it goes above the current $57k and gets as high as $70k, it might look a bit bullish for someone that's looking at buying for a short term but it's still reasonable to buy at that amount.
Simply put, whatever point you buy at is fine, as long as you are able to hold your asset until you can make a profit from it. Because people often delay buying Bitcoin, seeing that the price is quite high, but the longer they wait, the more time they will waste. So it's better to decide quickly whether to buy or not. Or if in doubt, investors can buy in smaller portions using the DCA method, and it is safer than the lump sump.
