These losses are based on in-game contracts that I partly refused to enforce
You stole close to 40 BTC from me (this sum does not include any interests, just the sum you took away directly by never executing my requested withdrawal, and running away with the funds then going dark).
As I said I am willing to forget the interests. However I expect payment of the principal in full.
"Running away with the funds", in my world entails that I have received them to my possession. This, however, never was the case. Is it possible to commit theft without gain?
Yeah, if you obtain an asset (in this case in-game) on credit, mismanage or otherwise fraudulently dispose of the asset, then make
another commitment to cover the debt in order to obtain even more credit, and then refuse to repay the loan.
Which is exactly what you did.
Pay your debts.
