(I am a newcomer) Discovered a new world, shorting USDC to earn funding rates, which have been positive in the long term. The overall annualized return should be around 5%; collateralizing LDUST also has an annualized return of over 1%, so combined, stable financial management can achieve an annualized return of 6%, crushing bank deposits in China. $USDC stablecoin can just be shorted once. $BTC
