Wait, so if I deposit more coins but do not withdraw, my current ~10k weight is gone ?
Edit: NM, it rests anyway on oayout it seems.
I've been thinking about this for a while but, how does Staking work exactly ? By that I just mean,how is it determined on what on earns?
Like right now my weight is north of 10k and I'm currently sitting on ~5.2k EGC.
All I truly understand is that you don't want to mess with / move coins around for staking to work.
You can move your coins, of course! But when you do so, the coin age is reset to zero days. Minimum coin age for EverGreenCoin is 1 day. What this means is that you will not be able to stake at the new address for 1 day and you will lose all the old coin age from the first address. Coin age is the biggest variable in determining weight. Weight determines frequency of rewards. All still equals 7% annual.
Actually it has less to do with the address itself. But rather transactional blocks or, more commonly called, coin groups. We, for the purpose of this discussion and as you asked, have been assuming one group.
But coins "at an address" are not what is staked, rather, coins "of a group" are. An address can have any number of groups. For example, if you are sent 1 EGC in a transaction from anywhere, it is a group. If you are sent 100 EGC, it is a different group. As far as stakig is concerned, it does not care of what address received the group, but that they are a group. Though the groups are organized by address.
When you send coins, you can optionally select what groups the coins will come from to make up the inputs of that transaction. This is called "coin control" and can be enabled by selecting "Options" from the "Settings" menu option, then clicking on the "Display" tab of the options dialog, then you will see the checkbox to enable coin control. After applying that change, you will notice you have some new options on the "Send" dialog of your wallet. Click the "Inputs" button now displayed on the sending tab of your wallet. You will see these groups and gain a better understanding how it determines on what one earns.
All that said, the short of it is that one earns on all mature coins held in an unlocked and fully synced wallet.
