My suggestion is go get a lawyer if

1. You are an American,
2. Contract was broken or any tort there.

This would be a easy case.

Or I don't know what you can do as I have 10 coins stuck in Ukyo's Weexchange.

As BTC goes higher and higher, we will see more and more people lose their dignity.

But I see this as a good thing. BTC worth nothing if it cannot figure out a way to build trust on selfish rather on dignity.
