Not much. About 0.1 BTC.
It's not so much the amount that is bothering me, it's the feeling of having something lost which now has the chance to be retrieved. I just have to find out if it is possible to get it back after such a long time.
You should be able to recover it, technically. But it's really up to Boussac and his integrity.
But all in all, he should provide you at least with a reply and a justified explanation if he declines to give you back your funds. But what he said was that as long as your balance is under 50 BTC which yours was comfortably under you should be able to receive a refund. The only thing that may be an issue is that he mentioned "in the first 90 days" claims are used to populate a form, and it's clearly been way past that stage. Again, he should at least give you a response so that you don't need to waste more time on this.
2 e-mails and enough time, but still no answer. Not nice.
You should PM him as well as emailing him. He has been online for sure though. Not sure what he's doing or if he's just ignoring you.
