If you want to know the effect, check what happened the first two auctions.
Only thing it contributes so far is some press coverage in the mainstream media.
I think I have already given my opinion on this through the below mentioned statement...

I highly doubt that there are people (whales) sitting currently thinking more of harming the price of BTC instead of giving it some support, as if these coins are sold and dumped, then that would be a better opportunity for many whales to get in again at very low prices as panic sell will be the obvious scene.
The only thing I saw was, dump first and a bit pump later on, still it harms the price of BTC a lot due to people selling in panic, as I have seen everyone selling on news.
