The BTC38 admins are incompetent.
I contacted them personally 10 days ago about this problem. At first, they didn't acknowledge that there was a problem, then they said that they contacted the ANC team. When I told them that I am part of the development team, they said that they didn't know how to contact us. When I told them that we have a web site with an email address (anoncoin.net), they said that the web site was down. Then they said it was not their problem to fix. Then they said they were fixing it. Then five days passed with no progress. I repeatedly told them to either restart their client, or to redownload the blockchain using the command anoncoind -reindex.
So, BTC38, like most other large exchanges, is not to be trusted.
I encourage you all to use exchanged.i2p instead.
