It can only be said that using spare money to gamble with the dealer, seeing whose patience is longer, the less it rises the bigger the explosion later, the dealer will not pull the market if they do not have enough chips, now many dealers are unwilling to pull the market, repeatedly washing the market to lower the average price, losing a bit to sell the goods, leaving a plate of retail investors here guessing whether it will rise or fall. This situation will continue until a stronger dealer comes to take over. Dealers without strength take chips downward, while strong dealers take chips upward, thus cycling.
