it's better to save it first because it's still in a worse value. it would be better if you wait to increase its value before you sell it. Even though the best decision to take this depends on you as you have your coins and money but with the current condition of ethereum and also the crypto market in general, selling now will only bring more losses but I would suggest that you hold patiently until the market recovers fully form a bear because when this happens
If you bought it when its still cheap below 200$ and you are now happy with some earnings you can sell it out, but if you are not satisfied yet and you
are a long term holder then wait till the value rise high, there's no impossible with crypto so better to think for a much better gained, there's a lots of
different speculations regarding to how this project will behave in the next few months before the year will be ended.
