Well I can confirm that I invested a lot more than 10k with BA through Minersource. Currently I have tried to work out something with Minersource but they have stopped responding to my messages. I will probably end up suing Minersource if they don't get their act together.
If there are any other people in the same situation as myself - please contact me, thank you.
See this thread. The more heat we can put on Minersource and Black Arrow the better.
