did he "legally" claim to have a certain amount of bitcoin (in this case 1 million) or is it just the assumption?
the article on Coindesk[1] only says "50 percent of the bitcoin that Wright held prior to Dec. 31, 2013" without mentioning any numbers. of course i haven't really been following the case, so maybe the value was mentioned before?
