hello it will take 7 days for the coins before they will be mature and begin to stake.
does it need activating multisend for stake?
You don't need to activate multisend to stake
MultiSend is a rebuild of what used to be called Stake For Charity (s4c). MultiSend allows a user to automatically send a percent of their stake reward to as many addresses as you would like up to 100% of the stake generated. The MultiSend transaction is sent when the staked coins mature.
You will have to unlock your wallet (check the checkbox for Anonymization and staking only)
