Which coin do you think will become next Ethereum?
Which coin do you think will become next Ethereum? by comparing all the factors including the community support, trading volume, use in daily life or business or anything which matters to make any coin on top of all the coins?
None. Ethereum is Ethereum and it was developed for its purpose. It may become an example of other project as a pattern but new projects cannot be like Ethereum. Maybe I am over confident of my opinion but that what I think even there are a lot of new coin in crypto space.
