Actually The down in the price was not the single news of dead of ETH owner , but there was also other reason that was the problem in the network algorithm of the ETH coin , after the problem in the network of the ETH coin , many people who bought ETH sold Thier ETH to remain away from any type of the loss , But with this news the mews of death of the owner also came in the market , this made really the ETH goes much down , but after the official declaration that the owner of the ETH is alive and news was fake , the price get increases.
But even today the people have not much trust with the network of the ETH , that how much time will take to repair and work again .
No doubt that ETH is really a cool coin and also many of the ICO haves tocken for the value of ETH coin only . Which is directly showing what the ETH coin is .
Here in my opinion also the ETH is best coin and after the btc we have the option of the ETH for bulk trade .
