Developers can create new coins using a method called “post-mining” after a cryptocurrency has been released but before it is open to the general public. As a result, the group can produce new currencies independently of outside meddling. This happens occasionally between snapshot dates, such as when token levels are calculated to allow a newly created coin to be dumped or traded on exchanges – but before code is made publicly available to allow outsiders to mine new currencies.
As an illustration, Bitcoin Gold (BTG) engaged in activity that many perceived as post-mining. Between the snapshot date and the first day of public mining, the project’s development team issued 100,000 BTG.
