Result
Currently the sending fee is set to 1 NUC, I am working on an update to reduce this fee, and to set the auto splittreshold a little lower. This will be done within 24hrs. So if you don't want high fees, you can manually split your coins with single transactions for now, until I am finished with the update. Just send coins to your own address the normal way.
