The price will slowly dwindle down and so will the volume. Anyone stuffing money in ETH at this point is either delusional, in denial, or were conned into believing it would someday rise again. The legalities haven't even set in yet. Wait until class action lawsuits enter the picture and a federal or state investigation begins.
Legalities? Under what country will they be brought???
Will the miners all over the world be sued? Could be be sued by the attacker or the Ethereum holder, or DAO holder?
