Over €6,000,000 at current prices.

And over €12,000,000 at the price 2 weeks ago.

Who knows what the price will be next week, but it won't be anywhere near €6,000,000 if they try to sell that much at once.

Though, the 24 hour trading volume for ETH is $1.5 Billion USD. So it won't affect the price as much as you'd think.

[imron]

$1.5 Billion, made up of many smaller transactions (~USD 15.5k on average according to this site [0]).

A number of large transactions to convert that much ETH to USD, would significantly affect speculator confidence, triggering others to sell.
