I'd never consider a coin that has gone thousands percent up from its initial price as a sleeping giant even in the slightest. The premise about this PoS switching is promising but doesn't necessarily make it any better than it's now.
It might be worthwhile going with the latter on this topic simply due to the fact there isn't much competition market cap wise for Ethereum from similar platforms and its recent upgrades now give it a ranking of second place under EOS by CCID's global blockchain technology ratings index so there's plenty of potential once the market realizes it
Quite the opposite I think, once people realizes that these platform like ethereum which shares the same category as EOS or anything out there gives no real meaning, it becomes overvalued.
