You still haven't accounted for the number of outstanding shares. AMC has 100M total. 40 M held by Kevin, 2 M sold, and 20M for a 'reinvestment account' (the same scam Ian Bakewell used, research it). The other 38M I assume are to be sold to raise money (AMC needs at least $2M in capital to cover their published plans).
So dividends paid to share holders will be 2/22 M = 0.09 of profits initially. Eventually this is diluted to 0.02 of profits, and Kevin holds voting right to do whatever he pleases.
Put that in your spreadsheet and understand why you should sell while Kevin is pumping.
Until 12 months or a dividend payout of 0.0005/share, AMC has 40M issued shares. Of those, any not sold are considered Growth/Expansion Fund shares.
On my spreadsheet I already accounted the 1/40M split in the "Dividends/share/month", so those are the dividends each share gets, independently of the amount of shares sold.
The Growth/Expansion Fund estimates assumes only the incoming dividends from 20M shares, so if there are only 2M sold, the dividends should assume 38M shares, almost doubling the available
BTC/month for growth purposes.
When AMC transitions to 100M issued shares, each share profits will decrease 60%. IIRC, Asicminer's dividends decreased ~71% when they exited the "shareholder protection" plan (0.00750846/0.02600008).
