By the way, any plans to have the issuer of the share get a portion of the trading fee?
Why would the primary issuer get a cut of the secondary market?
The issuer get the advantage that a secondary market gives them liquidity. If the issuer gets a cut, then the transaction fees must go up.
If the issuer wants to make a margin they can set up their own secondary market, but I'd never invest in them. I want them to stick to the knitting.
I guess you're right, what I had in mind is relevant for some specific use cases (for which there are better solutions) but maybe not in a broader sense.
