We are still waiting to know how such stocks / altcoins / tokens will be negotiated, as I imagine several investor might want to trade them as they do with other similar assets. Any update on this matter?
This is answered in the OP:
The distribution method is yet to be finalised and will be either via a new alt coin, counterparty, colored coins or some other method.
The decision will be made and implemented before the end of the ICO and your shares will be ready to be distributed immediately.
