60,000 of those are Atlas' accounts. Another 7,000 belong to goons. Subtracting scammers and their related sock puppet accounts, bitcoin has 5 legitimate users. Last year there were four, though; so at this rate it will only be about 43.5 years before there are 68,000 legitimate users.
That's actually funny.
It would be funny if it were not so sad. Seriously, there are at most maybe 5.25 legitimate users. So the ECB has nothing to see here and should just continue ignoring Bitcoin.
