I don't know why you want me to repay 0.6 BTC. It wasn't hacked by me, neither I knew it was hacked, neither we have proofs it was hacked. I don't have BTC now. Best I can do is send you 0.3 BTC in installments as I don't earn.
I will come online just once a week to payback installment, as I need to pay attention on studies more.
