Earlier quoted context omitted.
Are you suggesting that any given transaction is most likely to be a theft?
I think the point is that the only reason to transfer such a large sum of money is either buying/selling something or stealing. And considering there probably aren't many (if any) things one can buy with that many bitcoins, theft seems to be most likely scenario.
Perhaps you could be a little less specific?
>And considering there probably aren't many (if any) things one can buy with that many bitcoins, theft seems to be most likely scenario.
You could buy a lot of something from a private entity who really values Bitcoin.
