EGLD enters the room. Eth moves aside.
What do you mean by saying Eth is moving aside? Is that EGLD token not supported by the ETH platform so that if he enters the room, ETH will move sideways by itself? Hello bro, this is a world of crypto, not a world of children's games where when someone comes they will go away by themselves 
Hmmm where to start. You say children's games when obviously you don't know what you are talking about by saying that EGLD is on the ETH platform. EGLD has it's own ecosystem and is far superior in just about every aspect in comparison to ETH.
The topic asked which coin is the next Ethereum ? Obviously there can only be one ETH but if taken in the context of who will take over.... I believe without question Elrond (EGLD).
Do your research before you state that a coin is on Eth platform. EGLD is not.
