Staking Bucket

Select the amount of IOTX to be staked and voted to yourself.
Remember that the self-stake bucket has a 1.2 million IOTX minimum.
Select the staking duration next, and keep in mind that the longer the duration of your stake, the higher yield you'll receive.
Next, you'll be prompted to choose to activate the Stake-Lock which will yield a higher return, but won't allow you to unstake your deposit until the staking period of 365 days has elapsed after you disabling it.
