Pirate stole all the coins
I believe that is true but you must understand that there is still no proof. It is also likely that he pooled his own coins with the depositors' and put most of it to pirate. Then, when pirate stole the money, he assumed the stolen portion to be the depositors'. Most people I know would do the same. This is very realistic, especially if you consider the silly excuses he made when people discovered that he had coins sitting in his wallet, and the ginormous investors that no one knew about before that took a cut of all the payments.
That would make him a debtor for life
It is quite likely that he is still ahead.
Most importantly, however, Nick isn't and shouldn't give any one depositor special treatment.
No, the most important thing is, no one should be forced into a deal. It doesn't make sense to expect everyone to be content just because some people chose to agree to an unfair settlement. Everyone is free to claim what they deserve.
