Many people see through the VOXEL/USDT event of BITGET that the market maker is BG itself, thinking that BG is gambling with customers. Actually, this is quite normal. All exchanges have trading robots that provide liquidity. If all transactions are matched by customers themselves, then the candlestick cannot be seen; Market makers need to fill the gap between selling and buying, while using small orders at a large depth to ensure that you can buy when you buy and sell when you sell. On large currencies or exchanges with good liquidity, market makers have little risk because the number of long positions and short positions of customers at the same time is basically the same. The market maker robot is just making the 1m level K-line look good continuously. If customers trade unilaterally, the exchange can also sell their positions to other exchanges. However, if it is a small exchange, especially a single exchange coin (which is only listed on one exchange), the risk is high. Basically, the market maker or exchange is betting against customers. In extreme cases, all customers may go long or short, and the exchange or market maker cannot transfer their positions to other exchanges. They can only bet against customers, forcing profitable customers to reduce their positions or causing huge losses. So, if someone says they have earned tens of millions or even hundreds of millions in several second tier dramas, it's just a script. Just watch it and listen to it!
