Those bids are mostly fake; shared bids from Bitstamp.
How can that be? the asks don't seem to be shared...
Looking at the number of asks on Stamp it seems impossible for them to be shared with BFX
Bitstamp: 4300 BTC to 580
Bitfinex: 3500 BTC to 580
Asks are not being shared right now, only bids.
WTF

here's your manipulation boys (if true)
