So it turns out I've been doing the maths wrong. Very wrong. It's much easier to calculate.
TOTAL BTC spent on FeeShares is the BTC Value of the ShareCoins you used.
((Total BTC spent on FeeShares x 100,000) x 1000) / Number of FeeShares Owned = Daily Transaction volume SharexCoin needs to earn your investment back in one day.
(((Total BTC spent on FeeShares x 100,000) x 1000) / 30) / Number of FeeShares Owned = Daily Transaction volume SharexCoin needs to earn your investment back in one month.
(((Total BTC spent on FeeShares x 100,000) x 1000) / 365) / Number of FeeShares Owned = Daily Transaction volume SharexCoin needs to earn your investment back in one year.
So if you purchase 1 FeeShare for 0.07 BTC (ShareCoins valued at 350 satoshi each).
7,000,000 BTC Daily Transaction volume SharexCoin needs to earn YOU 0.07 BTC back in one day
233333.33 BTC Daily Transaction volume SharexCoin needs to earn YOU 0.07 BTC back in one month
19178.08 BTC Daily Transaction volume SharexCoin needs to earn YOU 0.07 BTC back in one year
i have this investment for fee share 0BTC how would you calculate that? i got the sharecoin for free / bought fee share from it.. thus i already have my roi the moment i bought that fee share.. no matter how small the income , it is counted as profit for me ^^, that's my story.. and other free sharecoin holder, but well if you bought sharecoins, it's a diff story,
Note this line:
"TOTAL BTC spent on FeeShares is the BTC Value of the ShareCoins you used."The point is, you can sell those ShareCoins and make money, so we are giving them a value, even if you gained them for free. The fact that you didn't pay for them doesn't change the fact that you would still be investing something with value.
If you spend 60,000 SHARES on FeeShare, then at 350 satoshis per SHARE your investment is 0.21 BTC, because you can always go ahead and get that BTC now... as it is yours.
