I have to disagree. Yes, there will be selling of ETH to fund projects, but if anything this is only a minor bubble. Long term, ethereum is going well above $100B market cap. Trust is the most important thing to consider, something you don't talk about. All the major corporations have their eyes on ethereum, and they're not going to suddenly switch it. The amount of development, money, infrastructure, and attention on Ethereum as a platform is simply to great to be taken over by a copycat project which no one has ever heard of. Take Bitcoin, for example. Bitcoin is technically worse than just about every single crap-coin out there - even those which are at $10M cap often operate much better and have upgrades the bitcoin maximalist would salivate at. But that doesn't really matter, because Bitcoin has trust, development, infrastructure, and money.
