I have come to understand something with the whole concept of buying low and selling high. Every trader want to buy low at a certain price without realizing the buying has to do with your own entry point and not what others think. Your entry point has to be determine by many factors, one of which is when you'll be targeting to sell. If you're targeting selling anytime within days or weeks then you don't have to rush into a declining market as there's every possiblity of further drop within that period but many don't take notes of this.
They blindly follow predictions of long term traders without realizing the reason for that entry point been emphasize on. In years or months to come the price is definitely going to be trading above that buy price but that can't be said about days or in weeks time, which is why you should do your analysis yourself and not rely on what you see online.
In crypto when you are a short term trader the idea of "buy low and sell high" becomes something a lot less relaxed, it is a very rigid concept. What you have to do or at least try to achieve is moving very quickly. Which means that if you really want to make a profit in one move inside of 10 days that means you will have to end up buying very quickly and selling very quickly, so the entry point does matter in that case, but when?
For example, when bitcoin drops from 50k+ levels to under 40k, then you will end up buying, so a 35k is a great price at that time and yes it did move up after that, you or a long term investor both should not be afraid. On the other hand we have been under 40k for a very long time, and then we are still not going up, which means that we should probably wait if we are in short term trading, whereas long term can still buy. So it is a lower price, but you have to wait, which means it is not about price, it is about past weeks or even days.
