For me, it is still better to hold ethereum, HOLD is still the best for this kind of market, selling at loss is really risky, it is really much better to hold than selling, just wait for the bull market, we are still in bear market.
Hold on to your Eth AND try to invest in other coins which have potential. Not too excited about Eth's future, actually. One obvious Ethereum weakness that can eventually weaken its claim on the "top spot" is that it lacks any way for developers to get their apps in front of end users, which is what they ultimately need. One coin, Byteball, is like Ethereum but it has an end user friendly interface and smart contracts anyone can read. Even a kid, honestly.
The bull market will come again but I think Eth won't get the lion's share of profits
