So I'm not totally sure what forum to put this under, but it sort of seems appropriate here.
I was looking through the block chain recently, for reasons of my own and I noticed something sort of surprising. http://blockexplorer.com/b/131227
Block 131227 had moved 133,232 bitcoins! And this was in a few mostly concentrated transactions, 49,000 in one, 29,000 in another, etc.
Then I checked back a little bit and again http://blockexplorer.com/b/131223
block 131223 130,015 bitcoins moved. 49k in one, 29k in another, etc.A lot of the nearby blocks have these huge transactions, 79,000, 125,000, 157,000 etc. So I was curious, maybe bitcoin has always been like that and I just haven't noticed, so I skipped back in time a bit. In the past day or so thre have been a ton of 100,000+ BTC transfer blocks, but in previous days past it has been almost totally unseen a volume of transfer that high.
Curious what people think of this, or if I'm just not familiar enough with block history that I'm missing something.
