Jumping in the air is a trapeze. The price of graphics cards has soared in the past two years because of mining, and profiteers hoarded and bid up the price. Many players can't buy it at the price of the graphics card itself. Now mining is no good, the price of graphics cards can't be maintained, and the profit of high-priced cards is too great, so profiteers don't want to reduce prices. Players hope that everyone will not buy it, and profiteers will not go bankrupt and jump off the building (flying trapeze in the air).
