This is where purchasing management is needed. If you come to the market, when you see the price has risen slightly, immediately buy it without waiting any longer. That's usually how it is.
However, we can change this condition of course. I think this also needs to be paid attention to. For example, if you have fresh funds in your wallet, make it a habit to let it sit for five minutes, while doing a price survey. If you have found a suitable one, it has potential and it hasn't gone up for a long time, at least it's been a month before you buy it and try to buy it in stages because there is a possibility that the price will be corrected again downwards.
