so in 69 minutes and 32 seconds you called this guy whom you know only little, reached him, explained the situation to him, clarified the hack, convinced him to return the coins, calculated an estimate return and wrote the lengthy statement...
are you kidding me?
You forgot one thing (not sure of its relevance until I see a reply(s)): What was the local time of which both parties were in when this took place? Was contact made my phone? (maybe two things) The millionaire just happened to be available to take your call? (maybe three things) The millionaire really felt threaten by your call? (maybe several more things)
