I don't think that matters because the keys are his and technically so were all the BTC in the keys at the time according to the code..
If he didn't return the 500 BTC that wouldn't be a scam then? Because the BTC was all his according to the code.
Well yes, that would be a breach of contract..
An interesting question is, while OG held the coins, did the forum own those coins, or just owned a contract?
I'm not sure.. What do you think?
I often look at it as, if you don't own the keys, all you own is a contract..
