Have you considered NAV/U control like BTCinvest?
This seemed to ensure value and share price were in alignment. This is something i would recommend
Can't say we're familiar with this. Didn't find much info about the mechanics when we searched but if you have a link to how it works we'll gladly look into it.
NAV is Net Asset Value and NAV/U Net Asset Value per Unit(share). So if a share price is 0.005 like in your case and cryptostocks takes 0.15% in fees when people buy shares then after the first share is sold and before you started doing any trades the start NAV would be 0.0049925 btc as that is the total amount your positions would be worth 0.0049925/1 (share). If you for example after a few days and with for example 100 sold shares (0.49925) and before the dividend is payed would have turned that to 0.575 btc then the NAV/U would be 0.575/100 = 0.00575 btc and if it was time to pay dividend to shareholders it would then be 0.0007125 btc, ignoring what fees would eat up on the way back to cryptostocks.
NAV/U wouldn't be that useful to report once a week or something thou as you are to pay out all profit either in the form of dividend to shareholders and the rest to the administrators anyway.
