Looks like the bidding is for two separate blocks, one with 20k and one with 30k bitcoins. A depost of $100k and $150k is also required to be eligible for bidding along with a bunch of other hassles.
Your looking at the info of previous Bitcoin auction. This time only 2,700 Bitcoins going to be auctioned, in one batch. So this auction is for rich people only, the same way as before.
