I'm not a lawyer, but I bet a good one could pierce the veil for weex. Didn't Ukyo, the person, claim that he wanted to sell his personal shares of active mining to pay back weex people. It may have been the loan, but I would look into that if I lost money.
Yes, he wanted to sell his shares to pay back part of his debts. Though ken slaughter stole the shares only to make all the coins coming from it worthless at the end.
If ukyo wanted to pay it back this way doesnt make a legal way to sue ukyo directly because the ceo of a company can pay with his private belongings but that doesnt make a right for others to be paid by his other private belongings.
An unregistered exchange is not a scam in itself, but by virtue of being illegal it is not afforded the protection of teh corporate veil. It can not enjoy bankruptcy protection any more than Dimebag Pedro could. Again, see
Piercing the corporate veil.
bitfunder was the exchange. Weex was a kind of wallet and weex is the company that lost coins. But even when this wouldnt be the case... it depends on what happened with the coins. He didnt sell shares for a company he owns. He only had a wallet that lost coins and an unregulated exchange. So what will you charge him that could make him personally viable? Lets say the coins vanished because they were stolen. I dont see how you could justify that he personally had to pay for it. Not to speak about if he could do it at all.
