It is true. In the past few months Ethereum has been really bad, and for several months now the ETH has seen so much of its price reduction and still it's still the biggest coin of all time. I don't know what the cause is, but this will take a while to improve Ethereum's situation to be able to stabilize again. Currently the repairs have begun, Ethereum continues to rise even though little by little, but I'm sure there will be a time later for Ethereum to stabilize again.
