On your service I received 1,5 BTC in day. 1,5*0,2=0,3 BTC in day. 47/0,3=157 days. About 5 months. And considering that in a way new BFL that quicker than 5 months.
Or you accept option of others more? Which simply keep silent!
So the following is true then:
1.) You noticed the bug and tried to steal as much BTC as possible.
2.) You then immediately went on to spend this withdrawn BTC.
3.) You then decided to deny doing any of this.
4.) You then accepted the facts that you did steal the BTC and still havnt returned it.
5.) You now make a proposal to inaba for how he could eventually recover the fund.
Its not acceptable to offer repayment of stolen funds over 157days minimum, with increase difficulty that would likely be closer to 200+ days.
Either you pay back what you stole right now or you will be treated as a criminal in this community, its as simple as that.
If you can lie outright from the start, do you expect inaba to believe anything you state now ?
