Ethereum now is in deep situation it's better to hold than to sell and loss your investment. Ethereum has a potential altcoin that can beat bitcoin in future. Nowadays many investors uses ethereum blockchain as a support in their projects.
Bitcoin is unlikely to win, but the fact that the price will rise in the future is a fact. Ethereum is very popular with people and it's not the time that such a strong coin could be easily buried. I am sure the ethereum will be very surprised by its price.
I think this was really the very best time to hold an ethereum or maybe it is better to buy more and hold. We need to take an advantage on this huge dip. Because we can now buy more ethereum in a very low price so I thi k the best thing to do is not just hold but buy more and wait for the right time to sell.
