IMHO when people will be able to liquidate their DAO ETH will dump hard and ALTS will drop too. Many people who bought ETH for the DAO pump are sitting in 50% + profits, not a bad gain to lock in.
so when will this happen? Funding of DAO ends on 27th but I dont think they can just cash out? So when is the first date when many can liquidate DAO?
You can dump on an exchange as soon as it starts trading, but to actually
withdraw your ETH from the DAO takes quite a while. I've read around a month and a half. First you have to split your shares from the main DAO, which takes time, then you would need to make and approve a proposal within your own DAO to pay out the ETH, and the proposal process a minimum required time period.
