What would happen to Ethereum after this big crashed? Is there no more chance to make it rise again? I hope that in this situation would be just a normal thing just like in bitcoin and will have the chance to rise again. For sure the dev will do something about it so I don't worry much.
Bitcoin, eth,ltc etc.. i mean the whole crypto is going down in value, but it doesn't means we won't see them rise again, we will. 
Do you expect a coin to just keeping on going up forever? Even after such a mega rally its been through you aren't satisfied? These are corrections and the market will soon recover.
Yes, exactly market will recover. though could take a lot of time.
