C'mon! I think i remember that quite some amounts were moved before black friday in the past years. They didn't even mention how many BTC were transacted, to which addresses, etc.
Maybe it even was an old dog from this forum, who went to somewhere in the world to dig out a long time hidden seedword list he left there once.
I would be scared if multiple "in-only" addresses where BTC were accumulated within the last 4 years would send all of their coins to a single exchange, but roughly 2.200 BTC? That's a tiny fraction of the total of the MtGox case addresses.
It was probably proudhon moving some of his stack.
I've got > 2000 and < 5000. Last year when I started I remember thinking "I hope one day to have 200". On then on the way down from $32 I kept scooping them up with my biggest haul coming in at $2.4x after the last $2.00 bounce. I keep saying to myself, "I've got enough", and I think I've got plenty, but it'd sure be nice to have 10,000...
