In the same position ...... but then I have taken the approach that this is a "stuff in the bottom draw for a few years".
On the other hand you could cut your losses and put the rest of the money into something that well return your loss plus some. At the end of the day no point having your dosh tied up in something that is going no where .... take the loss and move on or just forget it and hope that in a few years it will take off.
