#PI This coin only has two sides on the opposing order book: one is the project team holding a huge amount of coins with zero cost, and the other is the group of "spiritual victory" enthusiasts. When the "spiritual victory" enthusiasts stop buying pi, it means there are no opponents, and market makers cannot match trades. To maintain trading volume and avoid being delisted by the exchange, the project team has to trade themselves. Clearly, continuing to lower the coin's price is unwise because no one will take the other side, and panic will prevent third-party crypto investors from stepping in. Removing most of the sell orders and then using a small amount of funds to push the price up can attract "spiritual victory" enthusiasts to buy in, but this involves real capital costs for trading.
