Besides my opinion about paying out divends for expanding business, I have another questionmark...

How does the payouts work, if not all initial shares are paid?

Is it:

1.
BTCs * owned_shares / total_shares
or
2.
BTCs * owned_shares / (total_shares - left_of_initial_shares)

The second would be preferable though the divends should be based on the current investment made.

for example:
2000 shares is sold that gets us 10 rigs (example).
If the divends is calculated on 10000 shares that makes the divends based on 2 rigs instead of the 10 that the current investors have payed for. Only when all initial shares are sold, the divends can be based on 10000 shares.

I have trouble explaining this in a good way, Am I thinking all wrong here?
