What is the state of Witcoin?
Witcoin was written and run by mizerydearia. At some point he became unable to run the site, but he was/is unwilling to give the witcoin database or wallet to anyone else. (Someone else owns the domain name.) Mizerydearia was very intelligent, honest, and active, but it seems likely that he's developed some sort of mental illness (as you'll see if you read his forum posts). It's very sad. Hopefully he'll someday recover enough to run witcoin again or at least refund the BTC.
