Bunch of Adresses moving 50+k bitcoin in harmony

So i was just exploring some stuff. What i often do is chek a chart of the biggest bitcoin addresses and see which ones move the most and what moves they make. (http://ift.tt/1zDwn7G)

So today i became interested in the adress 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF and wondered where this adress was from, and why it has been holding 80k bitcoin since 2011/03/01.

Using google i found this old reddit post about MtGox possibly still having 200k bitcoin in different wallets. So i read trough it, found some other interesting adresses which the author somehow all related together. Most of these adresses all had 10k coins in them and they were all linked by some arbitrary transaction made to them, possibly to be able to easily identify them later.

So digging into this i saw that from many of these adresses recently a lot has moved: most of it on the same date and times and in the same fashion. 10k coins is moved to an adress, then 50 bitcoin is left and the rest is transacted onwards.

I was wondering if anyone could help me shed some light on this. I just though it was very interesting

EDIT: So i would like to include the original trail that started on this tread: http://ift.tt/2lo1uIx
