sorry if I am asking such a noob question but what happens if I sell my share to someone how are you going to know who has the share and how are you going to give the profit to the other person?
OP should explain it to you but i think for that we need Ethereum wallet features. Easy way.
Hard way you send e mail to owner in Monday i will transfer my DGX from wallet adress xxx to adress yyy please send me dividend BTC to address ZZZ...
Dividend are paid eg always on money at 11 you need register DGX adress that way once till you change balance of shares or buy new.
This is hard way.
Ethereum wallet should have special features to handle this easy by scripts written inside wallet.
I don't know how OP will do it but it is possible do do even without Ethereum wallet on small scale.
Yeah, we think with Ethereum it should be easier. We describe our first solution in the comment above.
