Sometimes, in order to achieve the effect of washing the market and absorbing funds, the official will take the initiative to press the good news, or even release the news of FUD, and wash the chips through the bad news. When the accumulation is almost complete, the good news will be released, and retail investors will get on the car and get off the car to complete the perfect handover. Sometimes it is even to wash out the big players in the chip structure, so if you buy a certain target, you can't exceed 1% of the chips at most, or even buy it by address. These should be the common sense of financial trading, but the accumulation of many common sense can cultivate one's financial literacy and step on many pitfalls.
