Serpens and KarkenTrader: The anomalous withdrawals in the ledger are your own withdrawals. We had some bitcoin withdrawals from a while back that were stuck in "sent" status, and this was fixed earlier, so they've gone to "success" status. A withdrawal in "sent" status is withheld, so you can't use the funds, but it isn't yet reflected in your ledger. It's only with "success" status that the withdrawal is reflected in your ledger. I'll PM each of you a list of the relevant withdrawal IDs. Of course, if you still can't make sense of it, let me know.
It's obviously scary to see unknown withdrawals in your ledger, but in this case it's nothing to worry about.
