no one deserves to be the next ethereum as long as ethereum still exists in cryptocurrency. being a coin as good as ethereum is not an easy thing, and not all coins can be like ethereum. then for waves it is impossible to get the title as the next ethereum.
I'm not sure why you mention Ethereum in this topic about *waiting or selling*, but I disagree with you: you can absolutely be the next Ethereum if Ethereum disappears from the market for some reason yet unknown. This market is hardly predictable.
