It is right for Binance to offer a commission reward for holding spot positions on Marscoin's platform. Otherwise, there would be a buying and selling tax on the chain, which is not available for spot positions on the platform. If everyone goes to buy on the platform, the amount of open space investment on the chain will only decrease. At present, only positions held within the institution can receive both on chain and spot commission rewards. Additionally, the announcement states that "the daily holding amount exceeds 10000 tokens", so it is best to hold 10001 within the institution to avoid not receiving rewards. Using Marscoin as an estimate, Flap has been distributing an average of around 300 spcxb tokens per day in the past month. By using the total amount of tokens instead of holding positions, the monthly return on this portion should be around 13u. The current trading volume of Binance spot is calculated at 30 million, and Binance's total holdings are approximately 47% of the total amount. The fee rate is calculated at 0.10% of the nominal amount, and the monthly return should be around 6u. The combined annualized yield of the two parts can reach around 16%. Considering the current 10% commission for short selling contracts, if both spot and on chain trading volumes do not shrink, it should be possible to hedge against it as a financial asset. Of course, the above are all estimates, and the exact amount depends on factors such as rates and the price of SPCXB.
