I am going to say it straightly, 0.05 BTC.
There is a panic now, you guys are not wrong, hard-soft fork, eth pos etc. bla bla bla.
But after the dust, eth will see an all time high. Sorry.
The DAO bad news is a big challenge to ETH. If this matter gets resolved, there is a good chance that ETH will continue its uptrend.
If this bad news drags on, there is a good chance this coin will follow the footsteps of Litecoin.
Unless something else replaces Ethereum as the leading marketcap for smart contracts, then Ethereum will recover as Bitcoin did after the decline to $7 or $1. Litecoin apparently lost its main raison d'etre which was those who were pumping BTC to $1200 needed a highly liquid coin to exit into and it had served as a home for displaced GPU miners when Bitcoin ASICs appeared.
This is assuming there isn't some insoluble technical issues, such as this one I opined about:
The only way it is fixed is by the ecosystem maturing and having a wide diversity of smart contracts (many of which have been well vetted) so that the failure of any one of them can't impact the ETH price significantly. And I think also Ethereum might have a problem where bad contracts can infect other contracts, so that may prevent the ecosystem from ever being NOT TOO BIG TO FAIL (I need to research this more).
