Do you agree with this assessment from the article or do you have more credible and accurate information?
The answer is coming from a guy who said "My Top List" so maybe it's his personal list quite not be accurate? You can easily find out which addresses hold the most bitcoin than their actual identity. I personally found this very disappointing,
It has been estimated by some that up to 40 percent of all possible bitcoins are lost.. lost keys, accidentally erased hard drives.
So the current market just runs on 60% of the bitcoins? Not sure if that information is accurate as well.
That is also what I am thinking, since it is hard to know who's bitcoin wallet is whose we can't really say that it is a fact. Unless someone proves it on their own, sending proofs and showing themselves unto the public, but I guess that is dangerous to them in security.
