My definition of $RARE is that Binance sees the market is not good, dare not list new coins, can only turn around and open contracts, activate market trading sentiment to earn handling fees, it wants to create a leader. (Open contracts to force shorts to earn funding rates). I calculated the account of yesterday's dog dealer. If it opens more than ten times, the funding rate is -2, and it lasted a day yesterday, just from the funding rate, the dog dealer can earn 120% of the principal of the contract in one day, plus yesterday's increase of nearly 50%, the dog dealer directly earns 6 to 8 times. Now it depends on whether this dog dealer has a big pattern. If the pattern is big, it will eat up the time when Binance changes the funding rate.
