If this one person/entity really owns 63% of the market and their currently hoarding it, I imagine that anything they do with their coins could have a huge impact. It might be worth ~100M USD but if they tried to cash out it would likely collapse the market. Even if they start circulating those coins, if not done properly could cause huge inflation.
I was looking at this part:
>Note that from the 1814400 BTC awarded, 1148800 BTC has never been spent (63%). I suppose (but have not checked it yet) that these are exactly the segments that belong to the mystery entity
So I guess I'm confused the market bigger than the 1,814,400 that have been awarded somehow? I'm not that familiar with bitcoins so that's very possible, but the author seems to imply that Nakamoto has 63%.
