So if we mine in the test pool today or before December 5th, once the mainnet is launched are my rewards mined before December 5 obsolete?
Hi. Yes, any rewards you get now will be invalid once Cash2 launches. Rewards are only valid if they are received after December 5, 2018 9:00 am EST. I often reset the test blockchain after making changes to the code base in order to test the new code. Also, Cash2 has no premine.
