Is there a micro-stock market investment platform that works in bitcoin?

[Giulio Prisco]

I am thinking of something like this:

- Users can buy micro-shares of public companies. For example a user can buy 1/100 of a FB share (currently trading at $93) for $0.93, and pay in bitcoin.
- The money is used to buy real shares. In the example, as soon as there are enough buyers for one FB share, the operator buys one FB share and the user receives 1/100 ownership.
- Users can trade micro-shares.
- Users can sell micro-shares to cash out. For example if 100 users want to sell 1/100 FB each, the operators sells a real share and pays the users.

Does something like that (or similar) exist?
