Many friends complained that they sold PFVS and barely made any profit. When I sold it, I also couldn't sell it and saw that the fees were very high. This is because PFVS is on the ETH chain (Ethereum fees are indeed expensive), rather than BSC. Later, I saw many group friends complaining, but actually using limit orders at that time could avoid high fees (the fee was only about $0.1). Of course, Alpha's limit orders are not very user-friendly; it seems that they require a one-to-one match with the counterparty. Even so, it's better than dozens of dollars in fees.
How to avoid:
1. In the future, try not to take on Ethereum chain transactions.
2. Use limit orders in Alpha.
