So, if GB R7 invoice amount was $6,898 my understanding of the breakdown is as follows:

Plus 10% additional penalty       $689.80

Less Bitmine Admin Fee            $30.00
_____________________________________
Refund amount                       $7,557.80

Bitmine.ch would purchase BTC and refund BTC to GB R7 which is then split to the share owners less the 1.5% fee.

Thomas, is this your understanding?
