This is another issue we need to work on. The dividends are being paid on all the 40m shares issued sold and unsold. This does not make sense for unsold shares to be paid dividends. Only sold shares should be paid dividends. I hope this can be changed so only sold shares can be paid dividends.
It's not supported by BitFunder. It only supports splitting dividends by all, even if they are not sold. That's why they must not be "created" at all, until they are about to be sold.
