Just to add… there is a slight miscommunication I feel in the documentation.The 2015 document titled “How Local and Delegated Harvesting Works” makes it sound like you only need 10,000 XEM in your wallet to harvest right away… But this is not the case. You need 10,000 XEM “vested” to be able to start harvesting.
The missing part is that the doc does not tell you that vesting takes place at 10% per day… so if you only have 10,000 XEM it will be about 50-60 days before you can harvest the wallet amount of 10,000 (if you never add anymore).
However if you have 100,000 XEM (10 times the amount listed in the document)- then after 1 day… 10% of your 100,000 would be vested and you would be able to harvest.
It leads a person to think they ONLY need 10,000 XEM in possession to start harvesting…but this is not exactly true as it takes 10% of the wallet balance up to 10,000 XEM to vest. You cannot harvest with less than 10,000 XEM vested.
There is a calculator here to help figure up the number of days it would take to vest 10,000 XEM with other wallet amounts. The document leads a person to think they only need 10,000 XEM… no, you need 10,000 XEM “vested” and that takes time before harvesting begins.
