If you take 1.0 BTC when its worth $80, is it proper to pay back 1.0btc, or $80?
i'm not trying to slag OP at all. i'm just wondering what happens when someone steals bitcoin, and then pays it back at a later date.
If you stole 1BTC then you owe 1BTC, unless you did a deal where you would pay a fixed amount in cash back etc.
Not necessarily.
