If we get an extra 1000 btc just from Cube sales and add that to our current wallet value, that's 1504 btc.
Only those two factors give us a dividend of BTC0.00376 per share.
Since 3000 cubes were sold at a retail minimum of BTC1 each, if all cube 3000 Cube sales are to be accounted for in this dividend, we could receive a rather large one.
