You should not be asking people such a question. You only have to options in surviving in this market, and that is either for you to be a long term investor or to be a trader and if you want to trade, you should go and learn when to buy and when to sell to be able to help you make a good decision than asking people what to do. If you are looking for profit, selling ETH is always a good idea if the current prices are more than the one you had paid at the time of purchasing ETH
I agree, I believe that the market has just started to recover and it will dump higher soon so you better hold and wait for the better value in the future. I'm also holding mine right now and hoping for better value in the future. I say that becuause Ethereum still has a long way to go to recuperate from its recent dumps
