Hi Alain:
Sorry to hear you are also having problems. Since posting the original post I've received messages from several other people in the same situation. I am starting up a 'group' to explore our options for getting in touch with Jered and/or Tradehill and seeking legal counsel.
I've sent you a PM so you can join our efforts.
Anyone else who has not been able to recover funds from Jered Kenna and/or Tradehill then please PM me.
If anyone knows of legal counsel familiar with bitcoin, asset recovery, liens, etc then PM me please.
Thanks
