i was just surprised when he said how its works in he's company there.... just the part when he said if he doesn't make 10% profit by the end of the month, that he paid from he's savings or previous profits etc
OK, if the previous savings are in multisig+escrow and you own a sufficient fraction of the signatures (half or more). As long as he shows actual possession of his own signatures. By signing a scan of his own passport or something with them.You don't want the guy ruined though, so hold back on the amounts.
EDIT If he's really up for it, it should be you to warn him in advance if you're a fair player (which I suppose you are).
