Thanks for the report. This is interesting. May I ask: How are those accounts keeping so much STEEM in the exchanges?
I really don't get it, how if we, as steemers, we should be a bit more smart, why they keep so much STEEM into the exchanges. Personally I believe this is wrong if is not there to make the prices go up. If one of those exchanges gets hacked, STEEM economy will be very much affected.
I guess some people here have other intentions than keep the STEEM economy growing...
