Racers have up to 3 staking options to farm their NFT box, from 1.5 hours, 15 hours, to 36 hours. The longer the NFT lock time, the higher the rewards!
Consider the time you join the races. If you participate in horse racing every day, the 1.5 hours option during breaks will be the right choice. However, if you only race on weekends, it would be great to stake your NFT with the possibility of 36 hours on weekdays to maximize your returns.
