Now this is till unconfirmed therefore we cannot just take this news and move forth. At the same time the article uses *CLAIMED* therefore the fact that he did have 1 million bitcoins is not something that is proven. I do think that even if he have died and no one knows where his bitcoins is, it would be more like *long term holding* until his family finds them and decides to sell.
Well the reason of death could also give us an insight into the whole thing, which I do not see happening since we have no confirmed article here about what has happened to him. Maybe he was killed because the person knew he owned so much and tried to steal them. Who knows ? Let us wait for a confirmed, detailed news.
