If one plans to earn money through staking rewards then this will not work for him but if one wants to invest in a token for a long time as it is potential . So if he does not hold freely those tokens and keeps them in staking, he will get some additional tokens from there which will give some support to his investment. This is the potential benefit of staking
Before saying this token is worth it to hold for long time, you need to check the price history first [1] as you can see after one year, did this token price is increase in the long run? nope. It keep decrease similar like fiat where inflation always happen in every year.
To be honest it looks like Betfury is slowly become inactive and doesn't have many improvement, unlike the beginning where they're active and many people are supporting this project.
