You've already listed the shares on an exchange without even specifying what you're doing with the money, what the risks are, what (if any) the buyback clause is, etc...
Seems to be the wrong order of doing things. It also makes me not want to use Cryptostocks if shares can be listed without any details about what they're for.
This is a good point, I was writing up a more detailed profile of funds to put up, simply put, It's my offer for people to get involved in mining on a smaller scale, At the moment you but in 50 coins and it's not sure if you will get it back after costs in 24 months, This is a way for anyone to chuck in a few 0.01's and still get a return, Although a small one, Still a return.
I am still working out details, I will add as soon as I can.
EDIT - What would a reasonable buyback % be?
