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.
Kinda sucks to see that anyone would just run away with such small amounts. Really deters me from wanting to give out loans to anyone. Hope he does come back though and repay the loan.
