I don't think if it's good if you continue to mine ETH since your miner is GPU's you can mine with other coins that I think have potential to grow than ETH.
Look at the other miners out there they are mining other altcoin than ETH because they know they can make profit compared to stay mining with ETH and honestly, I stop mining ETH because according to whattomine and coincalculator ETH is not profitable right now and most miners out there switching to Raven coin which is more profitable in Nvidia cards.
The other miner are mining new PoW coins because they know after 2 to 3 months the price will increase and if you mine the new coin I am sure that you can get higher rewards due to low difficulty compared mining on high difficulty so that you can hold your coins and sell after 2 or 3 months if the price increase more than 300% or more(Depend on the price).
