Your math gives total shares, but like i pointed out, It was a declaration on my part that 10000 NRS == 1 BTC == 1 Share, but that was not the price on the market was it? So we cannot assume that there is investment worth 50 BTC. The investment total was worth
29 BTC + 157 k NRB and 167k NRS +447 PTS (corrected)
Which at market price then was 29 BTC + 1.8 BTC + ~ 8 BTC and 4 BTC.
The SHARES are 50 but the VALUE is much less that your proposed 49 BTC
So what you are trying to tell me is that 29+1.8+8+4= 42.8 BTC is much less than 49.81 BTC, with your perceived value. Still even if I would take this into account 42.8 BTC is still a lot more than the around 32, maybe 33 BTC that was payed for the 5 miners!
Let's put the sarcasm aside a little and look at the facts. The shares are nearly 50 and their value, if you wish is 43 BTC (rounder numbers for ease)
Immediately remove the cost of the miners
33 BTC customs and taxes
7 BTC and the first two months electricity and the entire investment is gone.
