If you don't stake it you will keep having the same 1000 BC after a year, someone else with 1000 BC staking it will have roughly 1010 BC after a year. If you have a constantly up device with network connectivity staking is a good idea otherwise only worth it if you have a serious amount and care about the compound interest.
And of course, it helps secure the network to stake.
So it's more like 1010 for non-staker and 1010.1 for the staker I think.
Non staker (someone who never unlocks his wallet) will never get any additional BC so it'll keep being 1000. Now, if he decides to stake at least for a short while this will, over some short period turn into 1010....
That short period is like roughly 24 hours right?
Not 100% sure but, having not staked for a long while I received my 2 month worth of interest within an hour of staking, so you're most likely right.
