You have to hold Paytokens in your wallet to avail staking and for that you will get 10% annual returns and also they offer something only for 10 slots which needs 45K tokens and will give 50% as returns which seems shady to me.Better visit their ANN if it exists in bitcointalk to find the legitimacy of the staking process or its officially launched by the project team.
Only for 10 slots and will give 50% as returns? That's to much and i think 10 already filled by team themself. System like this not good for project, many people will talk negatively about an unfair stake system. Many people think this is great project but for me i will stay from unfair project like this.
