Many people don't know how to buy at the bottom, thinking that buying when the price drops is buying at the bottom, and often fall into a cycle of buying when the price drops, and then buying more when the price drops, which puts them in a dead end.
Finally, they simply give up buying at the bottom and go to the other extreme of chasing the rise. They chase without any rules, chasing when the price rises sharply, regardless of the type of the coin or the position it is in, and chasing the top again and again.
Over a long period of time, they completely lose confidence.
Chasing the rise and buying at the bottom must be guided by a set of logical ideas, and the technical relationship between quantity and price is the most timely and objective gold standard.
Those who understand understand, and those who don't understand may not agree.
