My guess is yes, the Bitcoin income is the same as last week meaning it includes the added hashpower, if this address had no new hashing power it would be a lot lower.
In short, the added hashpower has gained us a week.
Yes, this is the only address that we send mining revenue to. We will be reserving 50% of the new revenue for growth and expenses.
Will this "reserving for reinvestment" happen before the .0025 per share is paid out to shareholders?
Yes, this is one of the cost in the offering description.
Dividend payment
The global ActiveMining's income, including mining income, hardware sales via bitcoins, other cryptocoins and fiat transferred to bitcoins, will be paid to ActiveMining shareholders proportionally, after all manufacturing, maintenance, labor costs, R&D, growth and miscellaneous expenses are deducted. The first BTC0.0025/share dividends will only be paid to the first 10,000,000 ActiveMining shares, providing public investors a priority in getting back 100% return of their investment.
What we are trying to do is increase our mining and increase our dividends to our shareholders.
