Ethereum is a very good coin and it is also potential but I do not think it is dying anytime soon. The general crypto market is in red and it affects even the most potential coin but I am sure it will rise very high as soon as the market recover from the fall.
There's nothing best to do right now is just wait and time will come and ETH will bounce back, nothing to worry if you are holding this coin as long as you are holding and you are not doing any wrong decision by selling it out then chances of recovering or having a good profits is still possible to your account, if this coin will die it will die together with btc, but most of the time it bounce back when green market start to show up and more big investors place their money
inside crypto market.
