There are currently two staking options: flexible staking or fixed term staking. ## Flexible Staking In a flexible staking pool, users can stake and unstake any time, any amount, without penalty. This gives users who want the added flexibility and not have to lock up their tokens. ## Locked Staking In a locked staking pool, users have to lock their stake for approximately 14 days to not incur any penalties when withdrawing. See below for further details about locked staking: * Lock period is approximately 14 days * Additional stakes will reset the 14 day lock period * Early withdrawals will incur a 50% penalty. The fee will then be sent back to the fee pool and used for future rewards again * Once staked, users can see their approximate unlock date/time
