you cannot buy or sell these shares till the uplist
Not necessarily true. If you can arrange a private sale, you can sell your shares of ETC. Also, sometimes private companies will buy their shares for a set price based on an auditor's evaluation of the current stock price, which is based on the net asset value of the firm. JD will have to let us know if this arrangement will be available for ETC shares.
On the buy side, if ETC shares are offered in a private placement, they can be brought, but only by accredited investors (which probably includes few I-Hubbers, so it's not worth worrying about).
