Iam crunching away just like before. The good thing with gridcoin is that you are not just crunching something useless but data which really matters. Therefore I don't see this as an investment that needs to pay itself directly. It is a service to humanity and yeah you get some gridcoins as well ! So win win even if because of that mag unit decrease the payout of gridcoin is a bit less...
Don't react like normal miners with a normal cryptocoin....
