14. If I decide to subscribe for additional token instead of placing a buy order, will my additionally issued tokens be fungible with the previously issued tokens?

This depends on the structure of the Fund. If the Fund offers subscriptions at NAV, then yes, all issued tokens are interchangeable. If the Fund offers subscriptions into a new series, then no, your tokens are only fungible within the series. After your series has been consolidated, your tokens are fungible with all previous consolidated series.
