Well looks like it's overdue

quite sad because the account can earn 0.035BTC/week from bitmixer signature campaign, so the account is clearly worth more than 0.072BTC. OP got a bad deal here. he could've probably sold it for more.
The loan repayment will be fixed at 0.072BTC or $17 worth of BTC, whichever is greater. I'll hold onto the account for now as I don't like the idea of selling it or using it. I guess if OP doesn't buy it back I'll just abandon it.
