Here is a simple way to judge which coins should not be shorted

That is to see if there are trading pairs for perpetual contracts

In addition to USDT, are there any USDC contract trading pairs?

If there are, don't short it easily

This rule is currently valid, such as these

$SOL

$ORDI

$PEPE

In addition, the USDC contract is free of pending order fees. What does it mean? Simply put, if the order is eaten within 5 seconds after the pending order is eaten, it is not a pending order. If it is executed after 5 seconds, it is called a pending order. There is no handling fee, whether it is buying or selling, including closing positions

Don't close the position directly, set it a little higher, wait for the transaction, and then the handling fee will be charged

Do you understand?
